Glendalough is a glacial valley in County Wicklow, Ireland, renowned for an Early Medieval monastic settlement founded in the 6th century by St Kevin. From 1825 to 1957, the head of the Glendalough Valley was the site of a galena lead mine.

The General Post Office (GPO) in Dublin is the headquarters of An Post, the Irish Post Office, and Dublin's principal post office. Sited in the centre of O'Connell Street, the city's main thoroughfare, it is one of Ireland's most famous buildings, not least because it served as the headquarters of the leaders of the Easter Rising. It was the last of the great Georgian public buildings erected in the capital.

O'Connell Street is a street in the centre of Dublin, running north from the River Liffey. It connects the O'Connell Bridge to the south with Parnell Street to the north and is roughly split into two sections bisected by Henry Street. The Luas tram system runs along the street. During the 17th century, it was a narrow street known as Drogheda Street, named after Henry Moore, Earl of Drogheda. It was widened in the late 18th century by the Wide Streets Commission and renamed Sackville Street (Sráid Saicfil) after Lionel Sackville, 1st Duke of Dorset. In 1924, it was renamed in honour of Daniel O'Connell, a nationalist leader of the early 19th century, whose statue stands at the lower end of the street, facing O'Connell Bridge. The street has played an important part in Irish history and features several important monuments, including statues of O'Connell and union leader James Larkin, and the Dublin Spire. It formed the backdrop to one of the 1913 Dublin Lockout gatherings, the 1916 Easter Rising, the Irish Civil War of 1922, the destruction of the Nelson Pillar in 1966 and the Dublin Riots in 2006. In the late 20th century, a comprehensive plan was begun to restore the street to its original 19th-century character.

The Phoenix Park is a large urban park in Dublin, Ireland, lying 2–4 km west of the city centre, north of the River Liffey. Its 11 km perimeter wall encloses 707 hectares (1,750 acres) of recerational space. It includes large areas of grassland and tree-lined avenues, and since the 17th century has been home to a herd of wild fallow deer. The English name comes from the Irish fionn uisce meaning "clear water". The Irish Government is lobbying UNESCO to have the park designated as a world heritage site.

Saint Patrick's Cathedral in Dublin, Ireland, founded in 1191, is the National Cathedral of the Church of Ireland. With its 43-metre spire, St. Patrick's is the tallest church in Ireland and the largest.
