Holy Trinity Church, Millom

The earliest parts of the church are the nave and chancel, which date from the 12th century. Some details were restored in the 19th century, and the south porch was added in 1906. More drastic alterations were carried out in 1930 by Hicks and Charlewood of Newcastle, which included making the chancel wider. During this work, and incorporated into the northeast corner of the chancel, were part of a cross-shaft dating probably from the 10th or 11th century, and another ancient boss. Also at this time a west gallery was installed.

The church is constructed in stone rubble, with ashlar dressings, and it has slate roofs. The plan consists of a three-bay nave, a south aisle, a north porch, a smaller, lower chancel, and a small north vestry. On the west gable of the nave is a bellcote. In the north wall of the nave is a Norman doorway, and two round-headed windows. The south wall of the aisle has three three-light windows, and at the east end is a five-light window. The east window of the chancel has three lights. In the north wall of the chancel is a small 12th-century window, and the Anglo-Saxon stones have been re-set in the northeast corner.
