Govan Graving Docks, 18 Clydebrae Street, Glasgow

The Govan Graving Docks, located at 18 Clydebrae Street, Glasgow, represent an outstanding and unique complex of its kind in Scotland. Constructed between 1869 and 1898, the docks comprise three major dry docks, associated quays, capstans, bollards, pumphouses, workshops, and ancillary buildings, along with retaining walls, boundary walls, ramped accesses, and stairs. The dock walls and quay edges are primarily of grey granite, with whinstone setted working surfaces, while retaining walls and ramp sides are of cream sandstone. Cast-iron gatepiers mark the entrances.

The first dry dock (at the north end) was built by James Deas and Alex Lister between 1869 and 1875, measuring 551 feet long, 72 feet wide at the entrance, and with a depth to the sill of 22 feet 9 inches. It features stepped sides and a curved end that unusually curves toward the bottom. Nine sets of stairs with grooves for materials lead down to the paved base. A modern steel caisson gate provides access to the Clyde. Associated buildings primarily to the north include a pump house and sluice houses constructed with ashlar on a rusticated base, incorporating round-headed openings. A former boiler house is located to the north, and a pump room to the south, with pumps positioned below the building. A square brick accumulator tower with four oculus windows was added circa 1895. The sluice houses are small, square buildings of similar construction. At the entrance, two hydraulic capstans, manufactured by the Anderston Foundry Co., are positioned.

The second dry dock, centrally located, was constructed by James Deas between 1883 and 1886, with dimensions of 575 feet long, 67 feet wide, and a depth to the sill of 22 feet 9 inches. It has stepped sides and a vertically curved end, with four stairs giving access through tunnels and slides for materials. A steel caisson gate and folding bridge provide access to the Clyde. A small, flat-roofed brick pumphouse stands on the south side of the entrance, flanked by hydraulic capstans as at No. 1 dock.

The third dry dock, at the south end, was built by James Deas between 1894 and 1898. It is the longest of the three, stretching 880 feet long, 83 feet wide, and with a depth to the sill of 26 feet 6 inches. It also features stepped sides and a vertically curved end, with eight stairs offering access through tunnels. Projecting piers, originally with curved recesses for a caisson to subdivide the dock, are centrally located; the caisson has since been removed. A steel caisson gate and folding bridge open onto Prince's Dock canting basin. An associated pumphouse, situated at the southeast end of the site, is constructed of terra-cotta brick with red sandstone dressings and divided into two sections. The eastern section is flat-roofed with electric pumps in the basement and a gantry crane, featuring a tiled interior. The western part is wider and has a pedimented gable and slated roof with a ridge ventilator, housing a workshop and hydraulic pumps. A cast-iron commemorative plaque dated 1895 is present.

Various ancillary buildings, constructed mostly of red or yellow brick and spanning differing dates, stand around the site. Two workshops are located on the north quay, one on either side of No. 1 pump house. To the west, a woodworking shop (formerly a harbour workshop) and offices, a two-story building with 14 bays of red and yellow brick and a pend at the west end, along with a weighbridge (designed by A & W Smith in 1889), are located. A mechanics' shop (circa 1895), a one-story, 10-bay building of red and white brick with iron-framed round-headed windows and a wrought-iron framed roof, stands to the east, with doors featuring glazed fanlights on the north side. A small steel Scotch derrick crane is located at the north end of the site.
