7. Kilmainham Gaol

It was officially called the County of Dublin Gaol, and was originally run by the Grand Jury for County Dublin. Over the 140 years it served as a prison, its cells held many of the most famous people involved in the campaign for Irish independence. The British imprisoned and executed the leaders of the 1916 Easter Rising here.

9. Kilmainham Gaol James Connolly (Irish: Séamas Ó Conghaile; 5 June 1868 – 12 May 1916) was an Irish and Scottish socialist leader. He was born in the Cowgate area of Edinburgh, Scotland, to Irish immigrant parents. He left school for working life at the age of 11, but became one of the leading Marxist theorists of his day. Though proud of his Irish background, he also took a role in Scottish and American politics. He was shot by a British firing squad following his involvement in the Easter Rising of 1916. Connolly was sentenced to death by firing squad for his part in the rising. On 12 May 1916 he was transported by military ambulance to Kilmainham Jail, carried to a prison courtyard on a stretcher, tied to a chair and shot. His body (along with those of the other rebels) was put in a mass grave without a coffin.

19. The National Concert Hall (NCH) (Irish: An Ceoláras Náisiúnta) is a concert hall located on Earlsfort Terrace in Dublin, Ireland, close to St. Stephen's Green, and is the principal national venue for classical music concerts. Originally built for the Dublin International Exhibition of 1865, the structure was converted into the central building of University College Dublin (UCD) at the foundation of the National University of Ireland in 1908. When UCD began to relocate to a new campus at Belfield in the 1960s, part of the building was converted, and reopened as the NCH in 1981. Since then, the structure has been shared with UCD. In 2005 it was announced that UCD is to relocate all of its faculties to Belfield in the near term, allowing the NCH to develop a major expansion plan on the entire site, bringing it in line with international peers. Today the NCH is one of Ireland's National Cultural Institutions, under the aegis of the Irish Government's Department of Arts, Sport and Tourism and, as such, is grant-aided by the Irish Government. The NCH is a statutory corporate body, with a management team, and a Government-appointed Board. In 2006 the Concert Hall celebrated its 25th anniversary with a number of gala concerts and events.

The Archbishop of Dublin has his official seat in the other one, Christ Church Cathedral Dublin. The site of St. Patrick's Cathedral is said to be the earliest Christian site in Ireland, where St. Patrick baptized converts. A wooden St. Patrick's Church stood on the site from the 5th century to about 1191, when the church was raised to the status of cathedral. The present building, the largest church in Ireland, was built between 1191 and 1270.
