A simply two stage multi cache starting outside St Michael Church, Market Place, Malton, North Yorkshire

The church was built in about 1150, from which period much of the nave survives. The tower was added in the 15th century, at which time the nave was slightly shortened. The chancel was rebuilt in 1858, then in 1883 under George Fowler jones the south arcade and east end of the nave were rebuilt, two galleries were removed, and transepts were added. In 1966 the south side of the church was rebuilt, and in about 1986 the north aisle roof was replaced. The building has been grade II* since 1951.
Built of sandstone with a slate roof the church consists of a nave with clerestory, north and south aisles, north and south trancepts, a chancel with a north vestry and organ chamber and a south chapel, and a west tower. Inside, there is a 17th-century font, and there is a 20th-century screen between the nave and the south chapel.
