Glasnevin Cemetery, on the right-hand side of Finglas Road, is the best-known burial ground in Dublin. It's the site of the graves of many distinguished Irish leaders, including Eamon de Valera, a founding father of modern Ireland and a former Irish taoiseach (prime minister) and president, and Michael Collins, the celebrated hero of the Irish War of Independence. Other notables interred here include the late-19th-century poet Gerard Manley Hopkins and Sir Roger
Casement, a former British consul turned Irish nationalist, hanged for treason by the British in 1916. The large column to the right of the main entrance is the tomb of "The Liberator" Daniel O'Connell, perhaps Ireland's greatest historical figure, renowned for his nonviolent struggle for Catholic emancipation, achieved in 1829. The cemetery is freely accessible 24 hours a day. An impressive new museum has a "City of the Dead" permanent exhibition that covers the burial practices and religious beliefs of the 1.5 million people buried in Glasnevin. The Milsestone Gallery has exhibits on key historical figures buried here. They also run great tours of the cemetery itself.
