County Hall, formerly the Old Sessions House, is a municipal building in Sandling Road in Maidstone, Kent, England.

[1] The original design involved a symmetrical main frontage facing south west; the central section of three bays featured an arched doorway with a fanlight flanked by two narrow windows and there was a triple window on the first floor; the end bays of the central section slightly projected forwards.

[4] Invicta House, a six-storey hexagonal building was built adjacent to County Hall in order to create extra accommodation capacity in the 1960s.

[11][12] In March 2020 the county council announced that it was considering leaving the building and moving to alternative premises which would be less costly to maintain.

[13][14] Works of art in the county hall include a portrait of the Deputy Lieutenant of Kent, Lionel Sackville-West, 3rd Baron Sackville, by John St Helier Lander[15] and a portrait of the Governor of Bombay, George Harris, 4th Baron Harris, by Hubert von Herkomer.
