Summerhill (Irish: Cnoc Críonáin) is a primarily residential area of Dublin, Ireland, on the Northside of the city located roughly between Talbot Street, Gardiner Street, Mountjoy Square, Amiens Street and Ballybough. It is in the Dublin 1 postal district. It is one of the most densely populated and economically deprived areas of the city.
The area is known historically for containing a range of red brick Victorian and Georgian terraced avenues along streets such as Buckingham Street and Gardiner Street as well as for the Monto red-light district of Dublin and the Gloucester Diamond.
In the 19th century, the area became known for tenement housing and later in the 20th century these were mostly replaced with large scale social housing schemes. Streets such as Summerhill Parade were entirely demolished (c.40 5 storey Georgian houses) and replaced with social housing. In 1981 alone approximately 120 Georgian houses were demolished in Summerhill.
In 1992, the sculpture Summerhill Group was unveiled. It is a bronze work on Kilkenny limestone by Cathy Carman and was commissioned by Dublin Corporation as part of the Per Cent for Art Scheme. The work invokes the history of the street, before its redevelopment into a dual carriageway, when children would play on the street.
