Cathays Park or Cardiff Civic Centre is a civic centre area in the city centre of Cardiff, the capital city of Wales, consisting of a number of early 20th century buildings and a central park area, Alexandra Gardens. It includes Edwardian buildings such as the Temple of Peace, City Hall, the National Museum and Gallery of Wales and several buildings belonging to the Cardiff University campus. It also includes Cardiff Crown Court, the administrative headquarters of the Welsh Government, and the more modern Cardiff Central police station. The Pevsner architectural guide to the historic county of Glamorgan judges Cathays Park to be "the finest civic centre in the British Isles". The area falls within the Cathays electoral ward.
