Church of the Holy Trinity

The Church of the Holy Trinity is a parish church located in Ascott-under-Wychwood, dating from the late 12th century. It underwent alterations in the 14th century and was restored in 1857 by the architect George Edmund Street. The church is constructed of rubble with Cotswold stone roofs and features a two-bay chancel, a three-bay nave with a low north aisle, and a three-stage west tower topped with a plain parapet. There is a gabled south porch and a south transept, along with a vestry added to the northeast between 1857 and 1859.

The two lower stages of the tower and the side windows of the chancel are lancets from around 1200, set in wide reveals. The nave and north transept likely date from the same period but have 14th-century windows with ogee patterns. There is a north door from that period in the aisle and a late 14th-century stepped three-light lancet with cusped heads in the nave, which has been restored. The east window is reticulated, possibly designed by Street. The upper stages of the tower feature paired 15th-century lancets and crenellation. The south transept has square-headed two-light windows with stilted-arch lights on its east and south walls.

The south porch displays Norman impost capitals and a chamfered archway with pyramidal steps, while the inner arch is early 13th-century. A wooden priest's door with a shouldered lintel is also present.

Inside, the church has a four-bay late 12th-century arcade, with one capital featuring scallops, two square piers, and labels with pyramidal stops. The chancel arch and the arch to the south chapel are double chamfered with moulded caps, likely from the early 13th century. A notable feature is the triple sedilia, which has a foiled head arcade at the front, similar to those found at Shipton and Idbury, suggesting the same masons were involved. There is a 15th-century pillar piscina and a 17th-century communion table located in the north aisle. The font is an octagonal chalice type from the 15th century. The furnishings, as well as the roofs of the nave and chancel, were designed by Street, and a few low late medieval pews remain.
