Trebyan Forge

Trebyan Forge is a late 19th-century forge located in Lanhydrock. It is constructed from squared granite rubble with granite quoins and features a hipped slate roof with ridge tiles. The building has a stack at the left end and another at the rear, both with brick shafts.

The forge was purpose-built for the Lanhydrock estate and includes a main range with a stack for the furnace at the left end and a stack at the rear right. There is also a small store room located at the rear right and a front left wing designated for shoeing horses.

The exterior is a tall single-storey structure, with double doors raised in height on the front right and a window on the right side. The front wing has a door with an overlight on the inner side and a large multi-pane window on the left side. The rear features a large window and a single-storey attached store room with a plank door and a six-pane light. A large ventilator with a hipped roof is positioned over the main forge.

Inside, the forge remains fully operational with all original fittings intact. The stack at the left end contains a fireplace with granite sides and a brick hood, along with a stone hearth and a granite anvil block. The shoeing room has a cobbled floor, and the roof dates from the 19th century. This forge is an unusual survival, retaining its original purpose and fittings.
