History in Dublin

3Arena Dublin

Dublin

The 3Arena is Dublin's largest indoor concert venue, sitting right on North Wall Quay in the lively Docklands district. With a capacity of around 13,000, it consistently ranks among Europe's busiest arenas by ticket sales. Originally a warehouse building, it was converted into "The O2" arena in 2008 and rebranded 3Arena in 2014 after Three Ireland's takeover. The venue hosts world-class acts in pop, rock, comedy and musical theatre, and its waterfront location makes it easily accessible from central Dublin.

Abbey Theatre

Dublin

The Abbey Theatre is Ireland's national theatre, founded in Dublin in 1904 by W.B. Yeats and Lady Gregory to give Irish writers a platform during a time of fierce cultural debate. Premieres of plays by J.M. Synge and Seán O'Casey caused public uproar — the audience once rioted over The Playboy of the Western World. After a fire in 1951 destroyed the original building, it moved to the Queen's Theatre until the current building opened in 1966. The Abbey was the first state-subsidized theatre in the English-speaking world and remains central to Irish cultural life.

Ardgillan Castle

Dublin

Ardgillan Castle is a Georgian country house near Balbriggan in County Dublin, Ireland, set within a sprawling 200-acre public park managed by Fingal County Council. Built in the 18th century, the house overlooks the Irish Sea and is surrounded by formal rose gardens, wooded trails, and open meadows. The castle itself hosts guided tours and events, while the park is freely accessible year-round. It sits comfortably between Dublin city and the County Meath border, making it a popular destination for families and walkers from the greater Dublin area.

Ashtown Castle (Dublin)

Dublin

Ashtown Castle is a medieval tower house within the Phoenix Park in Dublin — the largest enclosed park in any European capital city. Built around 1430, it is one of the few surviving medieval structures in Ireland still located within a major city. For centuries it lay hidden behind the Papal Nunciature building and was only rediscovered during demolition works in the 1980s. Today it is a protected monument open to visitors, set within the expansive green of Phoenix Park.

Baily Lighthouse

Dublin

The Baily Lighthouse stands on the Howth Head peninsula, about 15 kilometres east of Dublin, marking the southeastern tip of the headland and the northern boundary of Dublin Bay. Dating back to 1814, it is maintained by the Commissioners of Irish Lights. Its distinctive white tower is visible from far out at sea. The coastal path leading to the lighthouse offers sweeping views over the Irish Sea towards the Wicklow Mountains. The lighthouse grounds are not publicly accessible, but the clifftop viewpoint near it is regarded as one of the finest panoramic spots around Dublin.

Ballyedmonduff Wedge Tomb

Dublin

The Ballyedmonduff Wedge Tomb is a megalithic burial monument from the late Neolithic or early Bronze Age, situated on a hillside of Two Rock Mountain in a forest north of Glencullen in southern County Dublin. Wedge tombs are concentrated in the western half of Ireland, making Ballyedmonduff one of the easternmost examples of its type. The site is a protected National Monument of Ireland. It offers a quiet place in the woods where thousands of years of human burial culture materialise, well away from the main tourist routes.

Barberstown Castle

Dublin

Barretstown Castle

Dublin

Barretstown Castle is a castle north of Ballymore Eustace in County Kildare, Ireland. It stands on the foundations of a late 12th-century Anglo-Norman fortification, carrying centuries of Irish history in its stones. Today Barretstown Castle is best known for the Barretstown Camp – a holiday camp for seriously ill children run on the extensive castle grounds. It was founded by American actor Paul Newman. The combination of historic castle architecture and a social mission makes Barretstown Castle an unusual destination in the Irish countryside.

Bective Abbey

Dublin

Bective Abbey is a medieval Cistercian ruin on the River Boyne in County Meath, Ireland, about 7.5 kilometres from Trim. Founded in 1147, it was the first daughter house of Mellifont Abbey — Ireland's very first Cistercian monastery. In the 14th century, the body of Hugh de Lacy, one of Ireland's most powerful Norman lords, lay in state at the abbey — triggering a political dispute between the monastery and the Archbishop of Armagh. The well-preserved cloister remains and towers date from the 14th and 15th centuries. Today the ruin is a free-to-visit Irish National Monument. It sits in a quiet river landscape and, away from tourist crowds, offers a contemplative window into Irish monastic history.

Blessington Street Basin

Dublin

Blessington Street Basin is a former drinking water reservoir in northern Dublin, which supplied the north city from 1810 until the 1970s. The grounds around the water were laid out as a public park as early as 1891, and following a full renovation in 1994 it is now one of the most tranquil green spaces in central Dublin. A small lake surrounded by trees, ducks, swans, and benches offers calm in the middle of a dense residential neighbourhood. For those who want to see a quieter side of Dublin, this is a serene counterpoint to the busy tourist centre.

Book of Kells

Dublin

The Book of Kells is one of the most important manuscripts in the Western world: a lavishly illuminated Latin Gospel book created around 800 AD in a Celtic monastery, likely on the Scottish island of Iona. The four Gospels are transcribed in careful calligraphy and decorated with extraordinarily intricate ornaments, animals, and human figures. It has been inscribed on the UNESCO Memory of the World Register since 2011. The original is housed in the Old Library of Trinity College Dublin, where it is on permanent display — one of Ireland's most visited attractions.

Brú na Bóinne

Dublin

Brú na Bóinne, the palace of the Boyne, is one of the world's most significant Neolithic landscapes. Located in County Meath north of Dublin, it encompasses over 90 monuments including the iconic passage tombs of Newgrange, Knowth, and Dowth, built between 3500 and 2500 BC – predating both Stonehenge and the Egyptian pyramids. The site holds Europe's largest collection of megalithic art: spirals, lozenges, and wave patterns whose meaning remains debated. Most famously, Newgrange is astronomically aligned so that the first light of the winter solstice illuminates its inner chamber through a precisely placed roof-box. The entire complex has been a UNESCO World Heritage Site since 1993.

Busáras

Dublin

Busáras is Dublin central intercity bus station and the headquarters of Bus Éireann. The building was constructed between 1946 and 1953 in the International Modern style and stands on Store Street near Connolly Station. It is officially named after Seán Mac Diarmada — one of the leaders of the 1916 Easter Rising — and is a protected landmark. The ground floor serves intercity buses to all regions of Ireland, while the upper floors house the Irish Department of Social Protection. Busáras is also a stop on the Luas Red Line.

Butt Bridge Dublin

Dublin

Butt Bridge spans the River Liffey in central Dublin, connecting Georges Quay to Beresford Place and the north quays beside Liberty Hall. It is named after Isaac Butt, the 19th-century Irish lawyer, economist, and politician who founded the Irish Home Rule movement. The bridge is one of the most heavily used Liffey crossings and a workaday part of Dublin city life. It attracts less architectural attention than the nearby Ha'penny Bridge or Samuel Beckett Bridge, but its namesake gives it quiet historical weight in the story of Irish self-determination.

Carbury Castle

Dublin

Carlisle Grounds

Dublin

Carlisle Grounds in Bray, County Wicklow, is one of the oldest football grounds in the world, opened in 1862. Situated just behind Bray DART station, it is home to Bray Wanderers AFC and is considered the oldest active ground of any club in the Football Association of Ireland. What makes it unique is its seaside setting — from some stands you can glimpse the Irish Sea. Occasional international fixtures, including Ireland rugby league games, are also held here.

Carrickmines Castle

Dublin

Carrickmines Castle was a medieval fortress in south County Dublin, built to defend the English Pale – the fortified zone of English control around Dublin. Its ruins lay directly in the path of the M50 motorway, sparking a fierce public controversy in 2003–2005 as archaeologists and heritage campaigners fought unsuccessfully to halt construction. Sections of the medieval walls and defensive structures were ultimately preserved within or beneath the M50 roundabouts. The Carrickmines case became a landmark example of the tension between infrastructure development and archaeological heritage in Ireland.

Castleknock Castle

Dublin

Castleknock Castle is the ruin of a Norman fortification on the grounds of Castleknock College, a Catholic boarding school on the western outskirts of Dublin. The castle dates back to the aftermath of the 12th-century Norman invasion of Ireland. Its Irish name, Caisleán Cnucha, echoes medieval texts that mention the hill as Cnoc or Cnucha. The remains are today embedded within the school grounds and largely inaccessible to the general public.

Castleruddery Motte

Dublin

Castleruddery Motte is a medieval earthwork in County Wicklow, Ireland, situated about 2 km east-northeast of Stratford-on-Slaney. Mottes like this one – artificially raised mounds that once supported a timber castle – were the signature fortification of the Norman invaders of Ireland. The mound sits on a hillside near the River Slaney and is designated a National Monument of Ireland. There are no standing ruins, but the mound itself is well preserved, conveying how the Normans imposed control over the Irish landscape through elevated strongholds.

Castleruddery Stone Circle

Dublin

Castleruddery Stone Circle is located in County Wicklow, Ireland, near the River Slaney west of Baltinglass. It is a relatively small recumbent stone circle and henge from the Late Neolithic period — an era when such circular enclosures were built in small numbers across Ireland for ritual purposes. The site is protected as a National Monument of Ireland. Two large quartzite boulders mark the entrance. Lying off the main tourist routes in a quiet rural landscape, it offers a chance to experience a prehistoric site without crowds.

Castletown House

Dublin

Castletown House in Celbridge, County Kildare, is the largest Palladian mansion in Ireland, built in 1722 for William Conolly, Speaker of the Irish House of Commons and the wealthiest man in Ireland at the time. The building follows a classic Palladian layout with a central block flanked by curved colonnades and wings. Among its notable outbuildings are The Wonderful Barn and Conolly''s Folly – a decorative baroque ruin Conolly had built during a famine to provide employment for local workers. Now owned by the Irish Georgian Society, the house is open to the public.

Christ Church Cathedral

Dublin

Christ Church Cathedral is the older of Dublin's two medieval cathedrals, with origins around 1031 when the Viking king Sitriuc Silkenbeard founded a wooden church on the site. The present stone structure was built in the 12th and 13th centuries and heavily restored in the Victorian era. The cathedral serves as the seat of the Archbishop of Dublin in the Church of Ireland (Anglican). Its crypt — one of the oldest surviving in Ireland — holds historical artefacts including the mummified remains of a cat and a mouse famously found wedged inside an organ pipe. Christ Church stands in Dublin's historic core, close to Dublin Castle and within easy walking distance of the Temple Bar quarter.

Conolly's Folly

Dublin

Conolly's Folly, also known as The Obelisk, is a Georgian structure near Celbridge, Leixlip and Maynooth in County Kildare, Ireland. Built in the mid-18th century by the Conolly family, owners of the Castletown Estate, it was reportedly constructed to provide employment for labourers during a famine. The arched structure topped with an obelisk is a classic example of a folly – a building with no practical purpose. Restored by the Irish Georgian Society, it is now a national monument in state care.

Croke Park

Dublin

Croke Park is the heartbeat of Irish sport – a massive stadium in Dublin's Drumcondra district with a capacity of 82,300, making it one of the largest in Europe. It serves as the headquarters of the Gaelic Athletic Association (GAA) and the home of traditional Irish sports such as Gaelic Football, Hurling, and Camogie. Named after Archbishop Thomas Croke, an early patron of Irish national sports, the stadium is deeply embedded in Irish cultural identity. From 2007 to 2009, it served as the temporary home for Irish rugby and football internationals while Lansdowne Road was redeveloped. Today, beyond sporting events, Croke Park offers stadium tours and houses the GAA Museum.

Deansgrange Cemetery

Dublin

Deansgrange Cemetery is one of the largest burial grounds in the Dublin area, opened in 1865 across 70 acres (28 hectares) in the suburb of Deansgrange, Dún Laoghaire-Rathdown. Since its opening, over 150,000 people have been buried here — making it comparable in scale to Glasnevin Cemetery and Mount Jerome. The grounds contain a rich mix of Victorian and Edwardian headstones, family vaults, and more modern sections, reflecting over 160 years of Dublin's social and religious history. Both Catholic and Protestant sections exist side by side, and the cemetery remains in active use today while functioning as a place of quiet reflection.

Dowth

Dublin

Dowth is a Neolithic passage tomb in the Boyne Valley, County Meath, Ireland, roughly five kilometres from Newgrange. Dating to around 3200 BC, it is one of three major passage tombs in the Brú na Bóinne complex alongside Newgrange and Knowth. As an Irish National Monument it receives far fewer visitors than Newgrange yet preserves equally impressive megalithic artwork. Notably, the tomb is aligned to the winter solstice sunset, when light penetrates the passage into the inner chamber.

Drimnagh Castle

Dublin

Drimnagh Castle is a Norman castle in the Dublin suburb of Drimnagh and the only remaining castle in Ireland with a continuously flooded moat. Water is fed from a tributary of the River Camac, keeping the moat filled as it has been since the Middle Ages. Built to a Norman design, the castle has been continuously inhabited since the early 13th century – an unusual record of survival in a country where many medieval structures fell to ruin. The interior includes a restored great hall with an open timber roof. Visitors who arrive expecting a grand castle and find a quiet suburban setting will be surprised by how intact and self-contained it feels.

Dublinia

Dublin

Dublinia is an interactive history museum in Dublin dedicated to the city's Viking origins and medieval development. It occupies the Synod Hall, a Victorian Gothic building adjoining Christ Church Cathedral and connected to it by a covered bridge. Opened in 1993, the museum features reconstructed Viking and medieval street scenes, archaeological finds from Dublin's Hiberno-Norse foundations, and hands-on exhibits covering everyday life in the medieval city. A viewing tower at the top offers panoramic views over the historic center. Dublinia is particularly popular with families, as much of the exhibition is designed for active participation.

Fishamble Street

Dublin

Fishamble Street is a narrow lane about 180 metres long in Dublin's oldest historic core, running within the line of the former medieval city walls and marking the western edge of the Temple Bar district. Its name comes from a fish market that operated here in the Middle Ages. Music enthusiasts know it as the site where George Frideric Handel conducted the world premiere of his Messiah in 1742, a fact commemorated by a plaque on the street today.

General Post Office Dublin

Dublin

The General Post Office on O'Connell Street is Dublin's most iconic building and a central symbol of Irish history. Built in 1814 in neoclassical style — the last great Georgian public building erected in the capital — it still functions as the main post office today. Its fame, however, comes above all from Easter Monday 1916, when Irish independence fighters seized the building as headquarters of the Easter Rising against British rule and proclaimed the Republic from its steps. Bullet holes and fire damage from the subsequent battle are still visible on the facade. Inside, a large bronze statue of Cú Chulainn commemorates those who fell in the uprising. The GPO is not merely a post office but a national memorial — an essential stop for every visitor to Ireland.
