[3] The new building was designed in the neoclassical style, built in ashlar stone and was completed just in time for a visit by King George III, accompanied by Queen Charlotte, in July 1788.

[4] The original structure was a two-storey building set well back from the High Street with a corn exchange in front.

[5] Three cells were created in the basement for use by the local police force in 1839, and a market hall was added in front of the original structure at around the same time.

[1] After those works had been completed, the completed design involved a symmetrical main frontage with three bays facing onto the High Street; it featured a rounded headed doorway with a fanlight flanked by round headed sash windows set in a tetrastyle portico with Doric order columns, which flanked the centre bay, and Doric order pilasters, which flanked the outer bays, supporting an entablature and a pediment, with a clock and two supporting stone statues in the tympanum.

[7] An Anglo-American garden of remembrance and riverside walk, intended to commemorate the lives of service personnel from both nations who had died in the Second World War, was established behind the complex in 1962.
