Church of St Thomas of Canterbury (also Clapham Parish Church, or Thomas à Becket) is a parish church and Grade I listed building in Clapham, Bedfordshire, England. It became a listed building on 13 July 1964.[1] Though the church can be traced back before A.D. 1000, there is no record of the original patron saint, Thomas Becket having been so well accepted.[2] The church is built in the Anglo-Saxon style, possibly early 10th century. There are narrow semi-circular-headed windows. The upper story is Early Norman. The parapet is 17th century. The remainder of the church was entirely rebuilt in 1861,[3] by Sir George Gilbert Scott.[4] It features a chancel, nave, and two aisles. The tower, which dates to the 11th or 12th century,[5] measures 26 metres (85 ft) in height.
