![]() The Liverpool master pilots had already been consulted about the necessity for a light on the shore at Black Point, or Trwyn-du, but no action was taken until late in the 1830s when Trinity House built the present station at a cost of £11,589. The lighthouse is situated on a low-lying rock surrounded by shingle beaches about half a mile south of Puffin Island. The circular stone tower is distinguished by three black bands. The lighthouse was originally manned by two keepers, however these were withdrawn in 1922 when the lighthouse was converted to unwatched acetylene operation.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 powerin 1996, work to modernise the station included the development of a unique operating mechanism to work the 178 Kg fog bell. |
