The current building, commissioned to replace the Old Town Hall, was designed by the London-based architectEdward William Mountford in the Renaissance Revival style and constructed between 1890 and 1897. The building was opened by Queen Victoria, using a remote control lock from her carriage, on 21 May 1897. The turning of the key in the lock triggered a light in the building which was the signal for three concealed men to open the gates. An extension designed by F. E. P. Edwards was opened by the Prince of Wales on 29 May 1923. The gardens were first laid out in 1938, following the demolition of St Paul's Church. Originally named St Paul's Gardens, they were immediately nicknamed the "Peace Gardens", marking the contemporary signing of the Munich Agreement. An extension designed in the Brutalist style was added to the east of the Peace Gardens in 1977; nicknamed The Egg-Box after its appearance, it was demolished in 2002.
Exterior
The design of the exterior echoed to a certain extent the architecture of the adjacent St. Paul's Church of 1720. During construction, the building was criticised for its expensive embellishments. The exterior is built of Stoke stone from the Stoke Hall Quarry in Grindleford, Derbyshire and is decorated with carvings by F. W. Pomeroy. The friezes depict the industries of Sheffield, and the 64-metre-high clock-tower is surmounted by a statue of Vulcan. Bells were never installed in the clock-tower, but in 2002 an electronic bell sound system was added to provide hourly strikes and Westminster-style quarter chimes.
Interior
The entry contains displays relating to and leads to the Main Entrance Hall with a grand marble staircase. This also has an Electrolier an electric chandelier, part of the original lighting of the building. The walls include friezes including a depiction of the slaying of the Dragon of Wharncliffe. On the first landing is a statue of the first Lord MayorHenry Fitzalan-Howard, 15th Duke of Norfolk. The first floor has a gallery running its length which can be divided into four sections by means of powered oak panels descending from the ceiling. The south room is the Lord Mayor's Parlour which is kept permanently divided. On the same floor is the oak-panelled Council Room and its antechamber, which has above its door the advice "Be Ye wise as serpents and harmless as doves", a religious quotation.
