St John the Baptist in Stockton has a chancel with a date of 1840 on the exterior. The nave, however, has two-bay arcades dating from the 12th century, a 15th century clerestory and a 19th century roof. The nave arcades were extended eastwards in the 14th century and the nave was restored in 1879. The lower part of the west tower may also date from the 12th century. The choir was built in the late Middle Ages and in the 19th century. The font may also be 12th century.

The DB records that the Bishop of Winchester holds Stockton and that there is a church there. Before 1172, Jocelin de Bohun, bishop of Old Sarum, granted the church to the hospital of St Crossat Winchester. This was confirmed by Richard I in 1189.

The font is rather crude. It may date from the 12^th century, but the 19^th century seems more likely.
