St. Brendan's Hospital was a psychiatric facility located in the north Dublin suburb of Grangegorman. It formed part of the mental health services of Dublin North East with its catchment area being North West Dublin. It is now the site of a modern mental health facility known as the "Phoenix Care Centre". Since the official opening of the Richmond Lunatic Asylum in 1815 the Grangegorman site has continuously provided institutional facilities for the reception of the mentally ill until the present day. As such the Phoenix Care Centre represents the continuation of the oldest public psychiatric facility in Ireland.
