Remains of Hook Quay, an important element of the 18th century coal industry in Pembrokeshire. Located in the inter-tidal zone on the south bank of the Western Cleddau, the stone built quay was constructed by Caesar Mathias Junior of Hook in 1791 to serve Hook Colliery. Shallow draught barges transported anthracite from Hook Quay downstream to larger ports such as Milford Haven. The quay is visible as a substantial masonry wall with a wooden framework to the north and a raised area of made-up ground to the south. The quay is c. 3m tall and the combined structure measures c. 40m north-south by 40m east-west.
