Description
The Church of St Barnabas, built in 1849 by James Park Harrison, is a Grade II listed building located on Church Avenue in Warmley. This large five-bay church is designed in the Decorated style and features a nave with aisles, a catslide roof to the north, and a pitched roof to the south. The plain west tower is supported by clasping buttresses and topped with a broach spire. A gabled vestry was added to the northeast in 1909 by H C M Hirst, and there is a gabled porch on the south side.
The church has foil-headed windows, mostly coupled on the north side, and sub-divided lancets with two ogee lights and a foiled oculus on the south side. The chancel is slightly lower and has two bays, including a priest's door. The east window features three lights with three foiled oculi in the tracery. Inside, the arcades are supported by hexagonal columns, and the chancel has a scissor brace roof. There are two wind lobbies at the north and south entrances, which include chamfered panels, cresting, and decorative strap hinges. Stained glass can be found in the vestry.
