Walney Lighthouse
The current building dates to the early 19th-century and is Grade II* listed as well as being the southernmost man-made structure in Cumbria.[2] Completed in 1804, the stone lighthouse and its attached cottages actually predate Barrow and its port.[3] The structure was built to replace a smaller wooden lighthouse that was constructed by the Lancaster Quay Commissioners in 1790 to aid in navigation towards the docks at Glasson close to Lancaster and the River Lune.The optical system (as renewed in 1846) was a clockwork-driven rotating array of four Argand lamps backed by parabolic reflectors, which gave a white flash once a minute.[7] It was also the last to be using a catoptric apparatus;[4] that year the reflectors were replaced by a modern electric light unit.
