Sport NI have keep a list of sporting and leisure facilities across Northern Ireland, including information on their ownership, location and the type of facilities available (number of pitches, sports hall, swimming pool etc), regardless of who owns or manages the resources.
Please see the following link for where this has previously been made available https://www.whatdotheyknow.com/request/sports_and_leisure_locations_in_3
