The Old County Hall building in the centre of Oxford is apparently often mistaken by tourists as a castle but was actually built in the 19th Century in a Norman style. The building still houses the Council Chamber and a courtroom of historic significance. The County Hall was built in the form of a castle because it is on the site of Oxford Castle which was built in 1071. Visitors can still see parts of the castle such as St George’s Tower and the Mound which are situated next to this interesting building.
