Arbour Hill is an area of Dublin within the inner city on the Northside of the River Liffey, in the Dublin 7 postal district. Arbour Hill, the road of the same name, runs west from Blackhall Place in Stoneybatter, and separates Collins Barracks, now hosting part of the National Museum of Ireland, to the south from Arbour Hill Prison to the north, whose graveyard includes the burial plot of the signatories of the Easter Proclamation and other leaders executed after the 1916 Rising. St Bricin's Military Hospital, formerly the King George V Hospital, is also located in Arbour Hill.
