The earliest part of the
Church of England parish church of
St Mary the Virgin is the 12th-century
Norman north doorway. The
Early English Gothic west
tower was built slightly later. The church plan, as existed and as chronicled in 1823 records, and in possession of John Wayland, esq. of
Woodeaton, had a large courtyard entered through two elegant gates with a cross fixed at the northern part. The southern end of courtyard also had a cemetery. The main church building comprised: The south porch leads to an
aisle that is lit by four two-light windows. Between the aisle and the
nave is a four-
bay arcade. The nave has three
clerestory windows similar to those in the north wall of the church. The nave
pews are 17th-century. The pulpit and reading desk are late 17th-century, added in the reign of
James II. The pulpit was refurbished in 1819 with cushion and cloth given by Lady Turner, bearing insignia of the Turner family. The nave had a
west gallery where there was a painting of the
Resurrection of Jesus. According to inscriptions it was given by the parishioners. of
Woodstock in 1697. and St Mary's also serves as the British Army garrison chapel. The nearby
vicarage dates from 1638. The Reverend
White Kennett (1660–1728) was vicar of Ambrosden from 1685 until 1708. During his incumbency, Kennett became tutor and vice-principal at
St Edmund Hall, Oxford and published a number of scholarly works. Kennett was also Rector of
St Botolph's Aldgate in London from 1700,
Archdeacon of Huntingdon from 1701 and
Dean of Peterborough from 1707. It therefore seems likely that Kennett may have been largely absent from Ambrosden in the latter years of his tenure. He relinquished the
living of Ambrosden in 1708. Kennett was consecrated
Bishop of Peterborough in 1718. ==Economic and social history==
