Penmon Lighthouse This is special to me as I can see it from my house, and it features in many seascapes that I have posted of the Menai Straits. When we arrived here from our circuit of Anglesey we knew we were on the home strait.The Welsh name for this lighthouse is Trwyn Du - Black Point. There had been a call for a light at this location for some years by master shipmen in the nearby city of Liverpool especially after the steamer the Rothsay Castle ran aground and broke up nearby in 1831 with 130 people losing their lives. The first lighthouse was erected in 1838, at a price of £11,589. The lighthouse was originally manned by two keepers, however these were withdrawn in 1922 when the lighthouse was converted to unwatched acetylene operation.Trwyn Du Lighthouse was converted to solar power in 1996, work to modernise the station included the development of a unique operating mechanism to work the 178 Kg fog bell. The present Lighthouse is 29m tall and was designed by James Walker and built in 1835-1838. It was his first sea-washed tower, and a prototype for his more ambitious tower on the Smalls.The Lighthouse has a stepped base designed to discourage the huge upsurge of waves that had afflicted earlier lighthouses on the site and reduce the force of the water at the bottom of the tower.Austere vertical walls, instead of the usual graceful lines of other rock towers, are probably an economy measure. The tower has a crenellated stone parapet, in preference to iron railings on the gallery, and narrows in diameter above the half-way point. These are a features used by Walker in his other lighthouse designs. The tower is distinguished by its original three black bands painted on a white background.Walker also pioneered, unsuccessfully, the use of a primitive water closet, comprising a specially designed drain exiting at the base of the tower. The stepped design of the lighthouse may have helped water exit the closet, but surges of seawater made its use difficult during heavy weather. To the left we see the two pilots' cottages.
