Holy Trinity Church, Casterton

It is an active Anglican parish church in the deanery of Kendal, the archdeaconry of Westmorland and Furness, and the diocese of Carlisle.

The architectural historians Matthew Hyde and Nikolaus Pevsner state in the Buildings of England series that "the architect was almost certainly George Webster".

[2] The tower is partly embraced in the nave, forming a baptistry; Hyde and Pevsner state that it is "undersized".

[3] It is supported by diagonal buttresses, the bell openings are louvred with pointed heads and hoodmoulds, and the parapet is plain with raised angles.

[3] Its east end has a coped gable surmounted by a cross, and contains three stepped lancet windows.
