Heritage Open Day: All Saints stands on the market square in picturesque Helmsley. According to the 19th century wall-paintings in the north aisle, a church has been on this site since AD 200. The present building, built on Norman foundations, was dedicated in 1838. All Saints Church is a beautiful church which dominates the centre of the town. It is Grade II listed, has a 10th century hog-back tombstone, and an entry in the Doomsday Book of 1086. The splendid chancel arc, one of the largest in Yorkshire, dates from the 12th century. The handsome building is the result of major restoration work in Victorian times led by Temple Moore and Scott Holland, with the stained glass and the murals from this period too.
