Glasnevin Cemetery was consecrated and opened to the public for the first time on 21 February 1832. The first burial, that of eleven-year-old Michael Carey from Francis Street in Dublin, took place on the following day in a section of the cemetery known as Curran's Square.
The cemetery contains historically notable monuments and the graves of many of Ireland's most prominent national figures. These include the graves of Daniel O'Connell, Charles Stewart Parnell, Michael Collins, Éamon de Valera, Arthur Griffith, Maude Gonne, Kevin Barry, Roger Casement, Constance Markievicz, Pádraig Ó Domhnaill, Seán MacBride, Jeremiah O'Donovan Rossa, James Larkin, Brendan Behan, Christy Brown and Luke Kelly of the Dubliners.
The grave of Michael Collins, the nationalist leader who was killed in the Irish Civil War in 1922, is among the most visited sites in Glasnevin. Around him were buried at least 183 soldiers of the Irish Free State. In 1967 their names were recorded on memorial around Collin's grave.
