Chapel

The building is a Roman Catholic Chapel, dating from the early 17th century, and may incorporate some medieval fabric. It was reroofed around 1850. The chapel is constructed of coursed rubble with roughly-shaped quoins and cut dressings, topped with a stone slate roof that was formerly lead. It has a simple rectangular plan with a narrower stair turret on the western side, designed in the Gothic Survival style.

The south wall features the stair turret and three bays. The turret includes a chamfered loop and a moulded string below a crenellated moulded parapet. The west face has a chamfered loop and a corbelled projection to the left. On the north side, there is a blocked doorway with a triangular head beneath an empty panel and chamfered loops. A bellcote is located behind the turret, featuring a triangular-headed opening and a moulded cap. The nave has an old boarded door on the south side in a moulded surround with a flattened triangular head, along with two chamfered single-light windows (the upper one leading to a former gallery) and a south-east window with three pointed lights in a square frame, complete with a hoodmould. The north wall displays three 3-light windows, with traces of a blocked door beneath the western window, and a built-in slab with a cross and the inscription "MARIA" in a moulded surround. The east end has a window with three pointed lights under a round-headed arch with a hoodmould, and a panel displaying the Radcliffe arms above. A Roman tombstone is built into the wall below, and there is a small loop leading to the Derwentwater vault just above ground level.

Inside, the chapel features old box stalls with fielded panelling, 18th-century altar rails with moulded balusters, and an old boarded stair in a chamfered surround. The four-bay roof has cambered tie beams that support purlins and a ridge, with the central tie showing mortices for the timbers of a former gallery, which was the Derwentwater family pew. There is a 17th-century iron-bound chest and clear leaded glass in all the windows. The Derwentwater vault, which is not visible, has a stone stair beneath a flag in the chancel and a ribbed vault.

This chapel is a rare example of a Post-Reformation Recusant Chapel, traditionally believed to have been financed with funds raised for the Gunpowder Plot of 1605. It became Anglican in 1733, and the Derwentwater Vault was cleared in 1874.
