Tregona Chapel Including Forecourt Area Wall and Gate Piers

Tregona Chapel, a former United Methodist Chapel, was opened in 1838. It features unplastered cob walls set on a slate rubble plinth. The cob walls on the west front and south side are covered with large rag slates. The building has a low-pitched asbestos slate hipped roof with red clay ridge tiles. It has a small rectangular plan and is a single-cell chapel with the entrance located at the shorter west end and a rostrum at the opposite east end.

The chapel is a single storey with a blind west front that includes a central doorway fitted with a 20th-century plank door and a small, late 19th-century gabled open-fronted shallow red brick porch. The tympanum of the porch gable is faced with a large piece of slate and features shaped barge-boards. Inside the porch, on the left side, there is a simple wooden notice board. The south side of the chapel has two large late 19th-century sash windows with margin panes and slate cills, while the north side has two large original 24-pane sashes, also with slate cills. The east end is blind.

The forecourt walls at the west end, likely from the later 19th century, are made of slate rubble with slate rubble saddle-back capping. The forecourt tapers towards the outer end, where there is a gateway with two small granite monolithic gate-posts topped with pyramids; the gate itself is missing. A nicely cobbled path leads from the gateway to the chapel entrance.

Inside, the chapel has a simple layout without a gallery, featuring plain plastered walls and a flat ceiling from which six gas lights are suspended. The original box-pews remain, complete with panelled fronts and shaped ends, along with a leader's pew in front. The later 19th-century rostrum at the east end has chamfered balusters.
