Holy Trinity Church stands to the northeast of the village of Little Ouseburn, North Yorkshire, England. It is an Anglican parish church in the deanery of Ripon, the archdeaconry of Richmond, and the Diocese of Leeds. Its benefice is united with those of five local churches. The church is recorded in the National Heritage List for England as a designated Grade I listed building. History The tower and chancel date from the 11th century, the south aisle, arcades and the chancel arch from the 14th century, and the battlements and pinnacles on the tower from the 15th century. In 1874–75 the north aisle was rebuilt to provide an organ chamber and a vestry, and the east window was altered, the architects being the Lancaster partnership of Paley and Austin. Also during the 19th century the porch was added. Architecture Exterior The older parts of the church are constructed in stone rubble, and the newer parts in dressed sandstone. The porch is timber-framed on stone, and the roofs are in stone flags. The plan of the church consists of a two-bay nave, north and south aisles, a south porch, a north organ chamber, a chancel with a north vestry, and a west tower. The tower is in three stages with an embattled parapet with pinnacles, a saddleback roof, and a weathervane in the form of a cockerel. On the south and west sides of the tower are round-headed windows. The louvred bell openings are in pairs and are round-headed. On the side of the south aisle is a gabled porch, with two two-light square-headed windows to the east of it. The east window of the aisle has three lights, under a lintel consisting of a re-used grave slab carved with a wheelcross. On the south side of the chancel is a round-arched priest's door between pairs of lancet windows. On the side of the north aisle are two three-light square-headed windows and the organ chamber. The vestry has a north three-light window and two lancets on the east side. The east window in the chancel has five lights under a pointed arch. At the west end of the south aisle are fragments of an early sculpture. On the gable at the east end of the nave is a finial consisting of a wheelcross.
