Church of St Thomas the Martyr, Up Holland

The church is constructed in stone, with slate roofs. Its plan consists of a four-bay nave with north and south aisles, a two-bay chancel with a crypt beneath, a polygonal stair turret leading to the crypt, and a west tower. The tower is in four stages, with diagonal stepped buttresses. It has a west doorway carved with masks, shields, figures and Tudor roses. Above this is a large three-light window containing reticulated tracery. The two-light bell openings contain louvres, and above them is a small top stage containing clock faces. The parapet is embattled with pinnacles at the corners. Along the sides of the aisles and at their east ends are 19th-century windows with reticulated tracery. The chancel has two-light windows on its sides, and a large five-light east window.[2]

Inside the church the arcades are carried on quatrefoil piers. In each aisle are two painted hatchments. The south aisle contains a Commandment board and two benediction lists, and the north aisle has the Royal arms of George I. At the west end of the nave is a churchwardens' pew dated 1679, and in the base of the tower is a churchwardens' cupboard dated 1720.[2] Also in the south aisle is a piscina with a double basin. There are fragments of medieval stained glass in a south window. The windows in the chancel were designed by Henry Holiday in 1884 and 1903–04.[6]
