Schoolroom, Castleton Old Parish Church

The schoolroom, built in 1808 and altered in 1885, stands alongside Castleton Old Parish Church. The church, no longer in religious use, forms part of a picturesque group with the combined stable/schoolroom/session house. It is a T-plan building constructed of rubble sandstone, with polished ashlar dressings and coursed ashlar to the north (entrance) elevation. Lancet windows are present, along with strip quoins, raised margins, chamfered reveals, and a moulded cornice.

The north elevation is three bays wide, with an advanced gabled bay centrally placed. A pointed-arched doorway is located beneath a tripartite window, and a louvred quatrefoil opening sits within the gablehead. An ashlar bellcote with a hoodmoulded opening and cruciform finial adorns the gable, along with two lancets on each return. Single lancets are present in the recessed bays. The roof is covered with grey slate and features slab coping, block skewputts, and conical ventilators.

The schoolroom and stable section is two storeys high, with a catslide roof and a single-storey extension to the rear. It has coped gabledhead stacks and small-pane glazing. A 17th-century carved stone is set into the north gable, bearing the inscription "Deo et ecclesiae, hodie mihi, cras tibi. WMS (Rev Walter Scott) 1621" in relief, accompanied by a heraldic shield inscribed with “MW.”

Adjacent to the north-west of the church is a single-storey, three-bay house known as Old Bankend House, along with a small pitched-roof annexe. A high, coped whinstone boundary wall surrounds the site, with a mounting block to the north-east.

The building is situated on the B6357, approximately one and a half miles north of Newcastleton, just beyond the junction with the B6399. Castleton Churchyard, located further north-east along the B6357, was the site of the original parish church from the 12th century until the construction of the 1808 building. The church's central location served the wider parish rather than the main population center. Materials from the previous church, built in 1777, were reused in the construction. The schoolroom fulfilled a combined role as a schoolroom, session house, and stables. The church closed in 1952 when the congregation moved to St John's Church in Newcastleton, and is currently in a state of disrepair.
