Copperhouse Dock

Copperhouse Dock is a former canal dock built around 1769 for the Cornish Copper Company, with 20th-century alterations.

The dock is constructed from vertically-set, coursed blocks of cast copper slag, or scoria, sourced from the company’s smelter. The lock walls at the western end are made of granite ashlar, and there are timber lock gates. The dock measures about 100 meters long and consists of two sections at an obtuse angle to each other, narrowing at the center. At the entrance to the western end, there is a lock gate, while the eastern end features a 20th-century bridge over a sluice, along with a culvert on the north side.

The battered retaining walls are made of vertically set scoria blocks laid in courses. The rounded entrance at the west end is constructed from granite blocks, complemented by cast-iron posts and timber lock gates. At the eastern end, the 20th-century concrete bridge incorporates some reused copper slag coping stones with a pointed section. Additionally, there is a round-arched culvert located on the north side of the eastern extent of the dock.
