Church of St Martin

The Church of St Martin is a Grade II* listed building located on Church Road in Lyndon. It dates from the 13th to 14th centuries and underwent significant restoration in 1866. The church is constructed of coursed rubble stone with quoins and stone dressings, topped with Collyweston slate and leaded roofs. It features stone-coped gables and a parapet on the nave. The structure includes a west tower, nave aisles, chancel, a north chancel organ chamber, and a south porch.

The tower, built in the 14th or 15th century, has three stages, a plinth, a west window with 19th-century stained glass, four two-light bell openings with transoms and hood moulds, and battlements. Inside, there is a 13th-century coffin slab in the floor of the tower and a double chamfered nave arch supported by corbels. The hood mould has label stops. The nave arcades consist of two bays from the 13th to early 14th centuries, featuring octagonal piers and double chamfered arches, with hood moulds and single central head stops on either side. The clerestory has three 19th-century windows on each side and a 19th-century roof.

The north aisle contains three 19th-century windows, an opening to the organ chamber, and remnants of a stair leading to the rood loft. The organ chamber is likely from the 19th century. The chancel is mainly 19th-century, featuring a coloured tile floor, an east window, and a south door. The south aisle has a 13th-century door with a hood mould and head stops, along with two 19th-century windows. The upper part of the south porch is from the 19th century, while the lower part is probably older.

Inside, there is a 12th-century font that transitions from round to square at the top, supported by short shafts, three of which have attached shafts. The reredos and pulpit, made of alabaster and created in 1856, feature sgraffito work. Externally, there is an 18th-century wall monument on the east wall of the porch and another on the south wall of the chancel dedicated to John Freeman, a former rector who died in 1796.
