Mumbles Lighthouse, completed in 1794, is a lighthouse located in Mumbles, near Swansea. The structure, which sits on the outer of two islands off Mumbles Head, is clearly visible from any point along the five mile sweep of Swansea Bay. Along with the nearby lifeboat station, it is the most photographed landmark in the village. The tower has two tiers and initially two open coal fire lights were displayed. These open coal fire lights were difficult to maintain and were soon replaced by a single oil-powered light within a cast-iron lantern.
