The Church of Englandparish church of St. Peter and St. Paul is late Norman, built in about 1180. The chancel is of three bays but only one of the six Norman lancet windows, that at the east end of the north wall, survives unaltered. At the end of the 13th century a two-storey extension was added on the north side of the chancel. The upper floor is a chantry chapel and the lower is a vestry. In about 1310 the east window of the chancel was inserted and at least two of the windows in the south wall of the chancel were enlarged in the Decorated Gothic style. At the end of the 14th century the north aisle was added, linked with the nave by an arcade of four bays. The large Perpendicular Gothic window in the middle of the south wall of the chancel was inserted in the 15th century, replacing the Norman original. The south porch was added in 1630, the clerestorey was added to the nave in 1636 and the north arcade was probably rebuilt in the same century. The bell tower was built in 1725, probably replacing an earlier one. The west gallery was inserted in 1735. The church was restored and the north porch added in 1871. By 1854 the tower had a ring of six bells, of which the two oldest were cast in 1638 and the remainder in 1679, 1683, 1729 and 1854. The bells were increased to a ring of eight, and in 2016 an appeal was launched to replace the bell frame and to increase the number of bells to ten.
Present day
The ecclesiastical parish now forms part of the Vale and Cotswold Edge team of Church of England churches, with the Team Vicar remaining responsible for Blockley and its outlying villages of Paxford, Draycott and Aston Magna, as well as the parish of Bourton-on-the-Hill. The church is used as St Mary'sRoman Catholic church in the Father Brown television series and the vicarage transformed into presbytery for Father Brown's residence. In 2017 the bell frame was replaced by John Taylor of Loughborough. At the same time all the bells were removed and cleaned. The tenor bell was recast, two new trebles added, and all the headstocks and other equipment replaced.
