Located in the heart of historic market town of Buckingham, the iconic Old Gaol was built in 1748 in the style of a castle, with later additions in 1839 by the famous local architect George Gilbert Scott. It is one of the key visitor attractions of Buckingham.

The purpose-built prison is now a museum, a tourist information centre, a gift shop which includes a selection of local interest books and a unique venue to hire.

The Old Gaol Museum tells the story of Buckingham and rural life, including the Flora Thompson Collection (Lark Rise to Candleford author) and Buckinghamshire Military Trust exhibits. A number of the original cells form part of the museum visitor's experience. The museum is one of the Jewels of Milton Keynes.
