Castleton Baptist Church

Castleton Baptist Church is an eclectic chapel built in the Italianate style, featuring a striking facade with a distinctive rose window and intricate polychromatic detailing in cream, blue, and red brick. The structure is made of red sandstone and limestone blocks, topped with a clay-tiled gabled roof that includes a bell tower and spire at the northwest corner.

The northern elevation has a central bay that projects forward, showcasing a large rose window framed by blue and cream striped brickwork, topped with an ogee-hoodmould and a fleur-de-lys finial. Below the rose window are two trefoil vents and a quatrefoil at the gable apex. This central bay is accentuated by red and cream banded end pilaster strips beneath a blue brick bandcourse, with continuous arcading in an Italian Romanesque style. Below the rose window, there is a blue and cream diaper pattern frieze above four vestibule windows, which feature round-headed, banded arches with foliated capitals. The entrances are set back on either side, framed by similarly banded end pilaster strips and round-arched doorways that include nookshafts, ogee hoodmoulds, and gabled coping, with boarded doors adorned with decorative ironwork. A continuous impost band runs across the front, with 2-light windows positioned above both entrances.

To the right, at the northwest corner, is a polygonal belltower, which is broached at the base and topped with a deeply bracketed slate spire. The side elevations are buttressed and feature four windows, with colored brick used only for the banding around the round-headed windows. At the rear, a former organ chamber projects, complete with a capped chimney, a small rose window, and an attached school hall and boiler house.

Inside, the church retains a 'U'-shaped gallery supported by slender cast iron columns, originally marbled but now painted grey, with a gilded scrollwork gallery front. Access to the gallery is provided by spiral stone staircases at either end, featuring simple cast iron handrails. The original pews are still present. Behind the rose window is a large open piped organ dating from 1902, with the former organ chamber at the far end now blocked. The roof is supported by cast-iron trusses, with a later inserted ceiling.
