The complex was commissioned to replace Cardiff's aging fourth town hall on the western side of St Mary's Street which had been completed in 1853. Following a design competition, the firm of Lanchester, Stewart and Rickards was selected to design Cardiff's fifth town hall and adjacent law courts in the Edwardian Baroque style. The contractor, E. Turner and Sons, used the world's first all-electrically operated building site, including eight 5 ton cranes to lift the stone blocks. The total building cost was £129,708. As Cardiff received its city charter in 1905 while construction was underway, the current building is known as City Hall. The new building was officially opened by Lord Bute on 29 October 1906.
Exterior architecture
Clock tower
The distinctive clock tower is in height and has a gilded dial on each of its four faces. The clock mechanism includes an hour bell and four quarter bells which are each inscribed with mottoes in English or Welsh.
Fountains and pool
In front of the entrance portico is a rectangular pool with fountains. The fountains were created to mark the investiture of Prince Charles as Prince of Wales in July 1969.
Memorials
On the southern side of the building are two memorials: the memorial on the right is dedicated to victims of the Second World War while the one on the left is dedicated to the Polish soldiers, airmen and sailors who gave their lives during that war.
Interior rooms, functions and art collections
Marble Hall
The first floor landing of City Hall is decorated with statues in Pentelicon marble of famous figures from Welsh history. These were funded by a gift from David Alfred Thomas, 1st Viscount Rhondda; the personages to be commemorated were decided by a competition in the Western Mail. The Marble Hall with completed statues was unveiled by David Lloyd George, then Secretary of State for War, on 27 October 1916.
This room has hosted royalty, international statesmen and diplomats, and can seat 500 diners simultaneously. It is used for miscellaneous ceremonies, conferences and events during the year. It is decorated with mouldings picked out in gold leaf, of mermaids and other sea creatures. Three large bronze chandeliers are contemporary to the original architects' design.
Council Chamber
This is located above the main entrance portico and directly below the main dome of the building. Hanging from the dome is a bronze chandelier designed by Edwin Alfred Rickards. The arrangement is unusual in that the seating is set in a circular pattern whereas normally British council chambers have semicircular seating. The chamber was designed to host Cardiff's Council meetings. The dome of City Hall is supported by four massive pillars of Italian marble with bronze Ioniccapitals. The chamber is paneled throughout in oak. The plaster work is by G.P. Bankart and the stained glass window depicts a personification of the City of Cardiff, by A. Garth Jones dated 1905.
In popular culture
The cover of the Catatonia single "Mulder and Scully" has a UFO above the building similar to the movie poster for Independence Day.
