Trewalder Methodist Chapel And School Room

This is a Methodist chapel with a school room and carriage house, built in 1803. It was enlarged in 1862 and partially remodelled. The building is constructed of slate stone rubble with a slate roof, featuring a hipped end to the front and a 2-span hipped roof to the rear of the chapel on the left, a gable end to the school room on the right, and a lower gable-ended roof to the carriage house on the right.

The plan reveals the remains of an earlier chapel in the southeast corner of the current building. The chapel was extended to the south in the mid to late 19th century. A contemporary school room, heated by an end stack, was added to the south, forming an "L" shaped plan. A carriage house and stable was added to the right of the school room, now used as a store and lavatory.

The chapel has a single-story design, accommodating a ground slope to the right. The main entrance features plank double doors. The school room has plank double doors flanked by an early 19th-century hornless sash window with 24 panes and a later 19th-century horned sash window with 24 panes. The chapel's left-hand side wall contains two 19th-century 16-pane sash windows. The lower range on the right, housing the carriage house, has yellow brick dressings. It features a wide segmental arch with plank double doors to the left and a plank door to the right. A round-headed window with radiating glazing bars is situated in the gable end.

Inside the chapel are simple pitch pine furnishings, renewed in the late 19th century, along with a late 19th-century rostrum and late 20th-century altar rails. A central valley is supported by cast iron columns. The school room has a 19th-century fireplace on the right-hand gable end, and a mid-19th-century register plate.

The site has historical significance, as John Wesley preached there in 1750, 1751, 1753, 1760, and subsequently biannually. The desk on which he is believed to have preached is preserved in the school room. The Methodist society was established in 1753.
