Haydon Old Church

Haydon Old Church is a former parish church with a chancel dating from the 12th century and a south chapel from the 14th century. The west end was added in 1882 by C.C. Hodges. The building is constructed of squared stone, which includes re-used Roman material, and features a stone slate roof. The chancel has a two-bay south chapel, with the south wall of the chapel containing a round-headed chamfered doorway and a three-light square-headed window with hollow-chamfered jambs and mullions, alongside an altered 12th-century single-light window. The east wall of the chapel has a 14th-century window with two cinquefoil-headed lights and flowing tracery above. The south wall of the chancel features a 12th-century single-light window that is round-headed and rebated externally, while the east wall has three similar windows, with the central window being pointed. The north wall of the chancel has a blocked narrow square-headed door. The west end, dating from the 19th century, includes two lancets, a stepped buttress, a two-light window in the style of the 14th century, and a large buttress that incorporates remains of the former east window of the nave's south aisle.

Inside, the 19th-century two-bay arcade leading to the chapel has a circular column and pointed arches. The east end features a projecting roll-moulded string that forms the sill for the east windows and supports the bases of circular shafts between the windows. While the shafts were likely renewed in the 19th century, the old capitals with volutes remain, though they no longer support arches. There is a plain aumbry at the east end of the north wall, and the church has a good 19th-century roof with heavy king-post trusses. The interior contains various 17th and 18th-century floor slabs and wall monuments, including an inscribed 14th-century cross slab on the south side of the chancel floor. Another cross slab has been re-used as an internal lintel for the south door, with fragments of other slabs set in the recess of the blocked north chancel door. The internal sills of the south windows in the south chapel are formed by pieces of 18th-century monuments with high-relief carving. The font is a re-cut Roman altar.
