St Mary's Church, Callington

The church is built of ashlar granite and rubble with slate roofs and set-back buttresses. The nave and chancel share a continuous roof, while the south aisle has a lower separate roof and the north aisle continues in line with the chancel, later extended by a 19th-century vestry. Much 15th-century stonework was reused in the later north aisle. The tower has freestone dressings, corner turrets with pinnacles, and a battlemented parapet.^[1]

The windows are predominantly Perpendicular in style, many restored in the 19th century. The chancel east window is largely Victorian work incorporating earlier masonry, and small two-light clerestory windows light the nave from above.^[2]

Inside, the church preserves a medieval wagon roof to the nave, restored in the 20th century, together with arcades of the 15th century and a rood-stair turret in the south wall. Victorian restoration introduced reseating, screens, a reredos, pulpit, and other fittings, while retaining earlier features such as a Norman font and a piscina in the south aisle.^[1]

The granite Altarnun-type font, dated by Sedding to between 1100 and 1130, may be the only surviving remnant of the earlier chapel.^[1] Notable monuments include the recumbent alabaster effigy of Sir Robert Willoughby (d. 1502) beneath the north arcade and a 15th-century brass to Nicholas Assheton and his family. Later memorials and stained glass in the north aisle commemorate local families and saints.^[2][3]

St Mary's originally served as a chapel of ease to St Sampson's at South Hill, which remained the mother church. Following local concerns about the distance to South Hill, St Mary's Church was consecrated for burials in 1438.^[3]
