there is no legal definition for Coolock, and so no definitive population figures, but it is one of Dublin's largest residential areas. It is crossed by the Oscar Traynor Road, running from the Malahide Road to Santry, and named for the War of Independence politician, later long-serving minister, Oscar Traynor. The majority of Coolock, excluding Ayrfield, was built-up by the then city authority, Dublin Corporation, as part of a programme of the phased inner-city slum clearance (between, roughly, 1952 and 1987). Dublin City Council calculates that addresses containing "Coolock" comprise the largest stock of local authority houses within its jurisdiction and the area is central to the linear range of local authority building that took place between the 1960s and the 1980s across Dublin's Northside - i.e. Ballymun including Poppintree, Kilmore, Coolock, Edenmore, Kilbarrack and Donaghmede. The permanent Traveller halting site estates (which differ in layout to traditional halting sites) of Cara Park and Dominick Park, found in the Belcamp area (along the N32) are among the largest halting site facilities provided by local authorities in Ireland. They contain an adult education centre and pre-school facilities for the local Traveller population, both located beside Dominick Park. At least one smaller, more traditional, Traveller settlement is found in the area, close to the Clare Hall Shopping Centre. King of the Travellers, Jim Watt, is a resident of this settlement. Amenities Public parks in the area include the Santry River Linear Park and in Bonnybrook the Stardust Memorial Garden which is dedicated to the 48 people who lost their lives in the Stardust nightclub. Parnells GAA club is based in Coolock village. Coolock is also a centre of local government activity, with a Dublin City Council major centre, NEAR FM community radio station, a Health Services Executive centre and a recycling centre.
