Church of St. Peter

The Church of St. Peter, now redundant, was built starting in 1763 by contractors William Toovey and Joseph Tuckwell. It was completed in 1767, with paving, pewing, and stucco work overseen by Sir Robert Taylor. A spire, designed by Sir Robert Taylor, was added between 1776 and 1777, and a chancel was added in 1904 by Sydney Stephenson.

The church features a flint plinth for the nave and ashlar stone for both the nave and chancel. The tower is constructed of knapped flint with stone quoins and bands, while the chancel has an old plain-tile roof and the nave has a Welsh slate roof. The structure includes a four-bay nave, an apsidal chancel, and a west tower, showcasing a Classical style complemented by a Gothic spire and Gothic Revival apse.

Notable exterior elements include a six-panel double door with a fanlight at the round-topped doorway on the west face of the tower, which has a damaged moulded stone surround. Each side of the nave features four round-arched windows with damaged keystones and impost blocks, and quoins at the ends of the nave. The eaves of the nave are adorned with a shaped cornice and a plain parapet. The apse has early 20th-century reticulated tracery windows and a rose window on its north side. Above the west door is a three-light Y-tracery window, and there is a panel inscribed "This church was finished A.D. MDCCLXIX, The Spire A.D. MDCCLXXVII." The tower has clock faces on three sides, except for the north side, and features an open-work stone Gothic spire.

Inside, the nave has a shallow segmental-arched coffered ceiling. There are late 18th-century font and pews, and the east window contains stained glass by Morris and Co. from 1918. An external wall monument to Sir William Blackstone and his family is located on the south side of the nave, featuring a Gothic-arched surround with three armorial shields at the base and an inscribed panel above.

Historically, this church replaced one that was destroyed during the siege of Wallingford in 1646. Sir William Blackstone was notably involved in the construction of the tower and spire and funded the southern clock face, which was visible from his residence, Castle Priory, now known as Castle Priory College.
