West Leading Lighthouse, Sinclair Road, Torry

A matching pair of mid-19th century cast iron, lighthouse-style leading lights, located approximately 240 metres apart on a northeast to southwest alignment at Sinclair Road, Aberdeen Harbour. They were first erected in 1842 to designs by harbour engineer James Abernethy and his cousin James Abernethy of Ferryhill Foundry and extended to a height of around 12 metres (40ft) in 1886/87.

The tapering, octagonal-plan towers are cast to imitate blocks of coursed ashlar masonry. They have a splayed base and a recesssed timber door with moulded panels and a circular window. Embossed plaques are located about halfway up the shafts (above the blocked earlier doorways). These read 'Erected by the Harbour Trustees 1842 - Thomas Blaikie Esq, Lord Provost. Alexander Hadden Esq, Master of Shore Works'. The lanterns are partially glazed and have octagonal roof caps with cast iron ball finial and wind-vane. The lanterns contain remotely operated electric lighting equipment. The southwest (inner) tower is set on a rubble masonry base inset with six steps.

The upper sections are constructed of vertically and horizontally jointed cast iron plates with bolted flanges, while the base sections are singularly cast in the round (Paxton and Shipway, 2007). The interiors have not been seen (2019). A sectional drawing of the towers shows a metal platform with a ladder access and a fitted cupboard at the base of the lanterns (Aberdeen Harbour Archives, 2013).
