The Mardyke (Irish: An Mhuirdíog) is an area in Cork city, on the northern half of the long western part of the island formed by the two channels of the River Lee near the city centre. It was historically left as open space, because the land along the north channel of the river is prone to flooding. From east to west these open spaces are: Presentation Brothers College, a boy's secondary school; the Mardyke ground of Cork County Cricket Club; Fitzgerald Park, which includes Cork Public Museum; Sunday's Well Lawn Tennis Club; and the athletic grounds of University College Cork.
