New College, Oxford. In about 1400 or shortly thereafter New College had a tithe barn built at Manor Farm in the village. Its plan is by , it is of nine bays and built of coursed rubble with ashlar quoins and buttresses. The roof is of Stonesfield slate and has raised-cruck trusses. The building has similarities with tithe barns at Swalcliffe and Adderbury, both of which were also built for New College early in the 15th century. It is a scheduled monument and a Grade I listed building. Upper Heyford's common lands were enclosed in 1842. New College still held the manor in the early 1950s. Church and chapels Church of England The village had a church by AD 1074. Inside the current Church of England parish church of St Mary is a 14th-century recumbent effigy of a priest in a 14th-century arched recess in the chancel. The church may have been rebuilt in the latter part of the 15th century, but only the Perpendicular Gothic west tower survives from that time. Major repairs to the roof and south aisle were made in 1668 and 1769, but by the 1860s the nave and chancel were in a poor condition again. In 1865 the church was demolished except for the west tower. A new church, designed by the architect Thomas Talbot Bury in a Gothic Revival interpretation of Perpendicular Gothic, was built in its place and completed in 1867. This Victorian building has very regular coursed masonry, which departs conspicuously from the traditional Mediæval rubble masonry of the tower and, presumably, the demolished parts of the previous church. Bury preserved only a handful of features from the Mediæval church: a Perpendicular Gothic window in the north wall of the chancel, a piscina, a tomb recess and a 14th-century effigy of a priest. St Mary's is a Grade II* listed building. The tower has three bells, the oldest of which is the tenor bell cast in 1624 by Richard I Purdue, who had foundries in places including Glastonbury and Stoford in Somerset. Mears & Stainbank of the Whitechapel Bell Foundry cast the second bell in 1866 and the treble bell in 1946. St Mary's has also a Sanctus bell of unknown date. St Mary's parsonage was designed by William Wilkinson and built in 1869. St Mary's parish is now part of the Cherwell Valley Benefice, along with the parishes of Ardley, Fritwell,
