Church Of St Mary

The Church of St Mary is a parish church located on the north side of The Green in Datchet. It dates back to the 13th century but was rebuilt and enlarged between 1857 and 1864 by architect John Raphael Brandon in the Gothic Revival style. A timber south porch was added in 1867. The only remaining part of the original structure is the dressed Old Totternhoe Stone at the end of the chancel, while the rest of the church is built from squared, snecked rubble. It features a steeply pitched clay plain tile roof with gable parapets and a moulded string course below the window cills. An octagonal broach spire is located to the north, adjoining the chancel, and has deep moulded, revealed, arched openings below the cornice. There is a projecting gable on the north transept.

Inside, the church has a plain aisled nave with five bays and a double aisle to the north, along with modern dormers in the nave roof. The stained glass windows were created by O'Connor between 1860 and 1865. Over the south door, there is a wooden coat of arms of Charles II, dated 1683.

Several notable monuments can be found within the church. On the south wall of the chancel, there is a brass plaque commemorating Lady Katherine Berkeley from 1559. A square bronze plaque with a marble surround and a bust above it honors Mary Wheeler from 1626. On the north wall, a brass plaque in a granite surround with a pediment commemorates Richard Hanbery from 1593, while a bronze plaque in an alabaster frame honors Christopher Barker, printer to Elizabeth I, from 1599. Additionally, there is a marble tablet with cornice moulding and brackets dedicated to Christopher Arnold from 1758. Flanking the arches to the vestry are a pair of 17th-century oral marble plaques with busts and cartouches, commemorating John Wheeler from 1636 and Hanbery Wheeler from 1633.
