14 Henrietta Street Museum
Enter a time capsule sweeping back nearly three centuries in Ireland’s history when you open the door and enter 14 Henrietta Street Museum, a social history museum located in Dublin. The handsome Georgian townhouse shows its age like any proud dowager. In its heyday (circa 1740s), this home welcomed the guests of The Right Honorable Richard, Lord Viscount Molesworth and his family for elaborate parties. Designed by Irish architect Luke Gardiner, the house segregates the public, private, and domestic functions.
See the drawing room where festivities were staged. But walk through the parlor door to see how this mansion turned into a 19th-century Dublin tenement. If you love history, architecture, or sociology, then 14 Henrietta Street Museum is a prerequisite for any study of Ireland’s path to independence. In just 150 years, this mansion built for Dublin’s most wealthy families turned into a hovel where 100 people lived cheek to jowl by 1911. Whole families lived in one room without running water. Docents lead the 75-minute guided tour, connecting the history of Dublin life over three centuries to the stories of people who called 14 Henrietta Street home.
Blarney Castle
Blarney Castle is one of the most famous historical sites in Ireland. Built in the 15th century, it has been a symbol of Irish heritage and tradition for centuries. The castle is famous for its Blarney Stone, which is believed to give the gift of eloquence to those who kiss it. This has attracted visitors from all over the world who come to experience this unique tradition. Additionally, Blarney Castle has witnessed significant historical events and has been a strategic stronghold during various conflicts throughout Irish history.
Constructed by Cormac MacCarthy, one of Ireland’s most prominent chieftains, the castle’s stone walls have witnessed the ebb and flow of Ireland’s complex past. Its strategic location made it a symbol of power and authority, guarding the region against invaders. While the castle was not a key location in battle, it was home to many sieges and skirmishes.
Visiting Blarney Castle is like transporting through time. The castle is well preserved so you can see what it was really like in Medieval times. Wander through the gardens before making your way to the top to kiss the Blarney Stone and get the gift of gab! Its architectural beauty and stunning surroundings also contribute to its importance as a historical landmark in Ireland.
The Burren
If you are looking for one of the best historical sites in Ireland then you can’t beat The Burren.
After all, this incredible karst landscape is situated near the Cliffs of Moher in the southwest corner of Ireland and can be visited as part of a guided tour from Doolin. In fact, many local tours offer a comprehensive trip to the Cliffs of Moher and the Burren.
Now, doing a guided tour is one of the best ways to quickly and easily enjoy all that the Burren has to offer since this area is vast and home to an incredible array of rock formations that were created by cracked limestone.
In fact, there are so many historic forts, ancient tombs, stone crosses, and stunning caves to explore that it’s impossible to see it all without a guide if you’re short on time.
In particular, Doolin Cave is well worth a look since you’ll be able to descend almost 200 feet into a giant limestone cavern that is home to the world’s biggest free-hanging stalactites.
You can also do a self-guided tour of Caherconnell Fort and see the incredible stone ruins while learning about megalithic tomb builders. Just don’t leave without seeing local sheepdogs at work since they are extremely helpful to local farmers in the region
Clonmacnoise
Clonmacnoise is a ruinized monastic site located on the banks of the River Shannon in County Offaly. It was founded in 544 AD by Saint Ciarán, a man believed to be the first saint born in Ireland.
The monastery rose to prominence in the 9th century. For hundreds of years, Clonmacnoise was a center for religion, scholarship, trade, and craftsmanship in Europe.
Clonmacnoise is one of the most important religious sites in Ireland. It remains an important site for Ireland’s Christian heritage. Pope John Paul II visited Clonmacnoise in 1979 as part of his trip to Ireland.
The site was originally built with wood, but starting in the 9th century stone buildings were slowly added. Today you can visit Clonmacnoise and marvel at the stone towers, peaceful River Shannon, and churches that make up the site. The stone structures are impressive not just in their size and numbers, but also for the intricate design elements you can see if you look closely.
The monastery is about halfway between Galway and Dublin, so you can easily make a stop if you take the M6 across the island. Plan to spend about 90 minutes exploring the site.
Dublin Castle
Sitting on the south side of the capital, Dublin Castle is one of Ireland’s most cherished historical sites. It was built back in the 13th century on a Viking settlement and has been standing ever since.
The castle was originally used by the British during the occupation of Ireland as their central office. After Ireland received its independence in the year 1922, the government at the time gained access to the complex, and they made it into their complex. It has remained under government-controlled and acted as a major tourist attraction in the city and one of the many free things to do in Dublin.
As mentioned, gaining access to Dublin Castle’s grounds is completely free for all visitors, but if you want to go inside and take a tour of the Medieval Area, State Apartments, and Chapel Royal, you’ll have to book a private tour from the reception.
In terms of when you can access Dublin Castle, it’s open every day of the week between 9.45 AM and 5.45 PM, and the last tour starts at 5:15 PM. While the tours don’t always sell out, I recommend you try to reserve your space online in advance to avoid any chance of being refused on the day of your visit.
Dunbrody Famine Ship
Visiting the Dunbrody Famine Ship is an immersive journey into the past. This ship holds a significant place in Irish history. It was originally built as a cargo ship. Then later that same year, the Irish Great Famine began, and it was turned into a passenger ship to transport people fleeing the devastating famine to North America. In 1996, the JFK Trust commissioned work on a replica of the 19th century vessel. You’ll also see a tribute to US President Kennedy’s ties to Ireland with the Emigrant Flame that continuously burns right in front of the Dunbrody ship. You’ll find the Dunbrody exhibit in New Ross, about 35 mins from Waterford (one of many great Irish coastal towns).
The ship replica and exhibit offer visitors a chance to step back in time and experience the conditions that these desperate individuals endured during their journey. Its reconstructed decks and interactive exhibits vividly illustrate the grim conditions faced by these families. With these exhibits and the guided tours, you’ll really gain some understanding into the harsh realities of life on board, including cramped quarters, limited food supplies, and the uncertainty of what awaited them. The Dunbrody famine ship is one of many historical attractions in Ireland that serves as a powerful reminder of the courage and resilience of those who sought a better life amidst immense hardship.
Glendalough
One of Ireland’s most famous sites when it comes to history is the monastic site of Glendalough. Nestled in a glacial valley, this ruined historical site dates from the 6th century.
Established by Saint Kevin, an Irish saint, Glendalough attracts tens of thousands of visitors each year who flock to explore the ruined monastic site, enjoy the tranquillity of the valley and wander the shores of the two lakes nearby.
Saint Kevin was a descendant of one of the ruling families of Leinster and once he finished his religious studies, he returned to the area of Glendalough with a small group of monks and together they founded the monastery whose ruins you can visit today.
Glendalough flourished as a centre for religious studies until it began to decline in the 13th century before being ransacked by English forces in the late 14th century.
What remains today are the ruins of this once great site and buildings including the famous Round Tower, ruined cathedrals and chapels, priests’ houses, and other buildings. Monuments near the upper lake can also be visited such as a church, St. Kevin’s Cell, and the remnants of mining from the 19th century.
Glendalough is a fascinating place to visit and makes the perfect day trip from the Irish capital if you are spending three days in Dublin.
Leap Castle
Leap Castle is a historic and famously haunted castle in County Offaly, Ireland. It is known for its intriguing history and its eerie reputation, making it a unique and captivating destination for those interested in history and the supernatural. One of the most intriguing aspects of Leap Castle is its reputation for being haunted, holding the title of one of the most haunted castles in Ireland and the world.
If you are planning to visit the castle, Leap Castle offers guided tours that delve into its rich history, architectural features, and paranormal legends. Knowledgeable tourist guides provide insights into the castle’s past and share the stories that have contributed to its mystique.
You will also have the opportunity to explore the various rooms and chambers of the castle. From the Bloody Chapel to the Grand Hall, the castle’s architecture and artifacts provide a glimpse into its past.
Also, Leap Castle has undergone restoration efforts to preserve its historical and architectural significance.
Leap Castle’s blend of history, mystery, and haunting tales makes it a standout attraction in Ireland. It offers a chance to engage with centuries-old stories and explore the history that has shaped this enigmatic fortress. Whether you’re intrigued by the supernatural or simply interested in experiencing a piece of Ireland’s past, Leap Castle offers a unique and unforgettable visit.
Kilmainham Gaol
Visiting Kilmainham Gaol in Dublin is not just a journey into the past; it’s an immersive and poignant experience that offers profound insights into Ireland’s turbulent history and its struggle for independence. It’s an impressive historic site right in the heart of Dublin.
Kilmainham Gaol is a symbol of Ireland’s fight for freedom. It housed countless Irish political prisoners, including key figures like leaders of the 1916 Easter Rising. Walking through its solemn corridors and stark cells, you’ll gain a deep appreciation for the sacrifices made by those who sought to break free from British rule. The guided tours provide a moving narrative of their lives and the events that unfolded within these walls.
The gaol’s architecture adds to its allure. It’s a prime example of Victorian-era penal design, with its striking stone façade and austere layout. The grandeur of the East Wing, in stark contrast to the grim West Wing, underscores the societal divisions of the time.
Kilmainham Gaol’s historical significance extends beyond its role as a prison. It served as a backdrop for pivotal moments in Irish history, and its decommissioning in 1924 marked the end of a dark chapter. Today, it stands as a poignant reminder of Ireland’s journey towards independence.
Kilmainham Gaol invites you to delve into Ireland’s complex history, reflecting on its struggles and triumphs. It’s a place that evokes empathy, deepens your understanding of the nation’s past, and underscores the importance of freedom and justice. For anyone interested in history, politics, or the human spirit, a visit to Kilmainham Gaol is an experience that resonates long after you’ve left its solemn walls.
Muckross Abbey
If you’re looking for a peaceful and historic spot to visit in County Kerry, then Muckross Abbey is definitely worth a visit. The abbey, which was built in 1448, is full of history and is located in the beautiful Killarney National Park.
One of the most impressive features of Muckross Abbey is the massive tree that stands at its center. This tree is said to be over 200 years old and is an important part of the local folklore. According to legend, the tree at Muckross Abbey was planted by a monk who had come to the area in search of a place to establish a monastery.
Over the years, the tree has become a powerful symbol of the history and culture of the region, and visitors come from all over the world to see it. Whether you are a history buff or just love exploring beautiful places, a visit to Muckross Abbey is definitely worth your while!
If you plan to visit Muckross Abbey, wear comfortable shoes, as the terrain can be uneven. It’s also a good idea to bring an umbrella as the weather in County Kerry can be unpredictable. That being said, the site is open all year round and well worth visiting, no matter the weather.
In addition to Muckross Abbey, there are plenty of other local attractions to explore in the area. For example, nearby Muckross House is a beautiful mansion that was built in the 19th century. Visitors can take a tour of the house and explore its stunning gardens.
National Famine Museum
The National Famine Museum is a part of the Strokestown Park Estate near Strokestown, Co. Roscommon. It focuses on Ireland’s most tragic chapter that changed history forever: The Great Irish Famine from 1845 to 1852, which caused horrible consequences for the impoverished local people and the rest of the poor population of Ireland.
Back in the mid-1800’s, tenants rented tiny, but very expensive pieces of land on the Strokestown Park Estate from their landlords, the aristocratic Mahon family. The peasants’ only food source was lumper potatoes, which could be grown anywhere, thanks to Ireland’s wet and boggy lands. But in 1845, blight infested the potato leaves and tubers while growing in the ground, so the potatoes became rotten and inedible. As a result, one million people in Ireland starved to death in only seven years. Moreover, the landlords evicted their tenants when they were not able to pay their rent anymore. So two million people were forced to flee overseas from 1845 to 1855, but the conditions on the ships were often unhygienic, and there was barely any food or water. So many people got sick or even died on the journey.
50,000 original documents written during the Great Famine are displayed at the National Famine Museum. Also, visitors can listen to recordings of contemporary witnesses talking about their suffering, which makes this exhibit even more moving than it already is.
Newgrange
There’s still a lot of mystery about Newgrange. Who were the prehistoric people who built it, and why did they construct this enormous structure? It’s these unknowns that make the site even more fascinating to visit!
What we do know is that Newgrange is an ancient tomb, made more than 5000 years ago, buried beneath a mound of earth with a single passageway as an entry. Rocks at the entrance and further into the tomb have been carved with megalithic art – and on the winter solstice, the rising sun shines straight down the passage to hit one of these decorated rocks at the back of the tomb, suggesting this was one of the most important monuments for the ancient people who once lived here.
You can visit Newgrange on guided tours that leave from the nearby Brú na Bóinne and take you right into the centre of the tomb. There are also tours that visit another nearby burial tomb called Knowth, constructed by the same people all those millennia ago. Newgrange is one of just two World Heritage Sites in Ireland, which gives you a sense of how important it’s considered to be, even if we still don’t know everything about it.
Rock of Cashel
The Rock of Cashel is a stunning architectural marvel and a beautiful historic site in Ireland. Perched dramatically atop a limestone hill in County Tipperary, the site is home to a collection of medieval buildings, including a majestic cathedral, an imposing round tower, Cormac’s Chapel, and a high cross. These structures represent Ireland’s rich ecclesiastical heritage and showcase remarkable craftsmanship.
It’s said to have been the seat of the Kings of Munster and the site where St. Patrick converted the King of Munster to Christianity by using a shamrock to explain the Holy Trinity. These stories add layers of mystique to the site.
Not only is it historical, but the panoramic views from the Rock of Cashel are simply breathtaking. The surrounding lush green countryside and rolling hills provide a picturesque backdrop, making it a prime spot for photography.
Visiting the Rock of Cashel also provides an opportunity to immerse yourself in Ireland’s cultural and religious heritage. The guided tours provide historical context and engage visitors with tales of kings, saints, and artists who shaped the region’s history. This historic site is a must-see for travelers seeking a profound and enriching experience in the heart of Ireland.
Skellig
Skellig Michael is a tiny Island located off the west coast of Ireland and is home to one of Irelands’ most important historical sites. The historical significance of Skellig is such that it is one of only two UNESCO World Heritage sites in Ireland. On the island are the remnants of a 1000-year-old monk colony. Make your way to the top and walk among the ancient beehive huts and other stone structures. The views of the surrounding sea from the top are second to none. As a delightful bonus, the island is inhabited by loads of adorable puffins.
This is a fragile historical and ecological environment, and it is of utmost importance to preserve this Irish treasure. A visit to Skellig is special and it’s a bit like winning the lottery since the tour is both weather-dependent and landing tours can be hard to secure. You’ll need to schedule a landing tour with a tour operator who has been granted one of just a few yearly permits to land on the island. (Do note that this island is rugged and there are several hundred treacherous stairs to get to the top. Exercise due caution when visiting Skellig.)
Trinity College
Trinity College is an iconic institution in Dublin, created in 1592. It’s Ireland’s premier university, and despite being right in the heart of the city, has a lovely calm atmosphere across its 47-acre campus.
The centrepiece of this venerable establishment is the Book of Kells, a medieval manuscript that dates back to the 9th century. It is on view in the Old Library’s Long Room, a majestic library room that allegedly inspired the library at Hogwarts in the Harry Potter books and movies.
This ancient text, with intricate detailing, contains the four Gospels in Latin. The origin of the Book of Kells is disputed, but it was written close to the year 800, most likely by the monks from Iona, an island off western Scotland and Kells, which is in County Meath, north of Dublin.
It has been at Trinity since the 17th century and on display for decades. It attracts in excess of 500,000 visitors a year. Two volumes can normally be seen, one opened to display a major decorated page, and one to show two pages of script. The delicate pages are usually turned every 8 weeks.
Secure tickets in advance and ideally early in the morning as the demand to witness this ancient book is considerable!
Bonus: Derry Walls, Northern Ireland
One of the best historical sites in Ireland lies just over the border in Derry-Londonderry.
The Walls of Derry are over 700 years old and make Derry the only completely walled city remaining in Ireland. The walls are fascinating to see and learn about, and they have become an important attraction in the city, and a popular one too.
Taking a tour of the walls is one of the best ways to learn about the history of the walls and the city, as most tours will extend their knowledge beyond the walls, and talk about Derry as a whole.
And as you might know, the city has a pretty deep history to cover! From the Siege of Derry to the Troubles, the city hasn’t had it easy.
Aside from the cultural side of the walls, they’re also extremely impressive- and beautiful too, really. Especially the gates. Some even consider them one of the best spots for Instagram photos in Northern Ireland.
If you want further proof of how significant the walls are, they are part of the UNESCO World Heritage Site of the “Historic City of Derry”. There’s no arguing with UNESCO- and the Walls of Derry are without a doubt one of the best historical sites in Ireland.

Ireland is a magnet that will keep drawing me back now that I have finally visited. I highly recommend the Henrietta Museum to learn more about the economic history of Dubliners in the second half of the 19th century. Our docent was excellent.
Great post! I spent a week in Ireland a few years ago and loved it – but I didn’t get the chance to visit many of these. I’ve now got a great reason to go back!
