Squatting in the Republic of Ireland is the occupation of unused land or derelict buildings without the permission of the owner. In the 1960s, the Dublin Housing Action Committee highlighted the housing crisis by squatting buildings. From the 1990s onwards there have been occasional political squats in Cork and Dublin such as Grangegorman, the Barricade Inn, the Bolt Hostel, Connolly Barracks, That Social Centre and James Connolly House.
