The new City Hall was designed by Alfred Brumwell Thomas in the Baroque Revival style and constructed in Portland stone. The incredible building cost £369,000 to complete, the equivalent of around 128 million pounds today but remains an extraordinary beacon of success and civic pride for Belfast. Belfast City Hall is Belfast City Council's civic building. It is located in Donegall Square, in the heart of Belfast city centre. It first opened its doors on 1 August 1906. The guided tour takes place on the first floor of the building, however, lift access is available.
