Summerhill (Irish: Cnoc Críonáin) is a primarily residential area of Dublin, Ireland, located on the Northside of the city. It is located, roughly in the area bordered by Gardiner Street in the West, Mountjoy Square, Ballybough in the North, Northeast and East, and Talbot Street and Amiens Street in the South and South East. The name stems from the eponymous street of Summerhill Parade.
It is one of the most densely populated and economically deprived areas of the city.[1]
