Church Of St Mary

The Church of St. Mary is a church dating back to around 1100, with significant fabric from the early 13th century, the 14th century, and a north aisle and vestry added in 1849. It is located on the High Street in Weedon Lois. The church is constructed of limestone ashlar along with coursed squared limestone and ironstone, and has a lead roof and a 20th-century old tile roof to the porch.

The west wall of the nave and the lower part of the tower retain herringbone masonry from around 1100. The chancel's remains are from the early 13th century, while the majority of the building dates to the 14th century. South-east chapel windows are Victorian. The south-east chapel features a Decorated window of three lights with Reticulated tracery. All windows in the south aisle are Decorated, featuring two lights with flowing tracery and ogee hoods with carved finials. A priest’s doorway, marked by an ogee-headed arch, is found within the second bay from the right. The decorated south porch features continuous mouldings to the entrance arch, with a similar inner doorway and a 19th-century double plank door. The west window of the nave is decorated, but incorporates Victorian tracery. The lower stage of the tower is Norman, while the upper stage is Perpendicular with a castellated parapet and bell openings of two cusped lights.

Inside, a decorated recess is situated below the east window of the chancel; it was restored in the 19th century, and includes some reset carving featuring an ogee hood with crockets and a finial, flanked by crocketed pinnacles. K. Lewis has suggested this may have once been a shrine dedicated to St. Lucien. The tower arches are 14th century, except for the one to the north, which is 19th century. These arches are characterised by half-octagonal responds and double-chamfered arches, with hoods having head stops. The south-east chapel contains a 14th-century double-chamfered arch opening to the chancel and a similar arch to the south aisle, with large head stops. A Decorated piscina recess in the chapel has a crocketed ogee hood. A piscina is also present in the south aisle, featuring a recessed area with a crocketed hood and large head stops. The south aisle also houses two 14th-century tomb recesses with continuous mouldings. The roofs are 19th-century. The church is home to a Romanesque, circular font with leaf carving and beaded lunettes. A stone pulpit, dating to 1849, is a copy of the octagonal Perpendicular pulpit at Bloxham church. Fragmentary medieval wall paintings depicting two seated figures are found within the south aisle.

Historically, there was a priory at Weedon linked with the abbey at St. Lucien in Normandy. This church served as the priory church, with monks reputedly bringing relics of their patron saint. A well dedicated to St. Lucien (also known as St. Loys) was located south of the church. The priory was closed in 1414.
