The structure, which is the offices and meeting place of Somerset Council, is a Grade II Listed building.

[1] During the early part of the 20th century Somerset County Council was based at the Shire Hall.

[4] The design for the three-storey building involved a recessed concave main frontage of nine bays facing the corner of Park Street and The Crescent from which wings stretched back to the south west and south east; the central section featured a round headed doorway with coat of arms in the tympanum.

[1] It was extended to the south in the 1960s to a design by Goodwin & Tatham to cover most of the open land to the west of The Crescent.

[1][4] The Earl of Wessex visited County Hall and planted a tree to commemorate the 50th anniversary of The Duke of Edinburgh's Award on 25 April 2007,[6] and, following the amalgamation of The Light Infantry into The Rifles in February 2007, a ceremony was held at which the Queen's Colour and Regimental Colour of the 6th Battalion (Somerset and Cornwall) The Light Infantry were placed in the entrance of County Hall in June 2009.
