Treen Methodist Chapel Including Forecourt Walls

Treen Methodist Chapel, built in 1834, is a simple rectangular structure with associated forecourt walls. The chapel is constructed from painted granite rubble with granite dressings, topped with a scantle slate roof covered with gable ends and crested clay ridge tiles. Cast-iron gutters run along the roofline. The layout features a rectangular, aisle-less space with access at the southwest end and a rostrum at the northeast end, which is considered the ritual east end. A small rectangular courtyard sits in front of the main entrance.

The southwest-facing front features a central doorway, now with a 20th-century door, and a shuttered oculus ventilator above the gable. Each side wall has two windows; the original right-hand wall retains 12-pane hornless sash windows, while the left-hand wall has later sash windows with horns. The rear wall has a central window opening which has been blocked. The forecourt is enclosed by granite rubble walls with dressed granite copings, and a gateway aligned with the main entrance.

Inside, the chapel has plain plastered walls, a central ceiling rose, two numbered pine pews (numbers 8 and 9), 19th-century benches, and a panelled pulpit with a canted front, moulded cornice, and a bow-fronted ledge.
