Trwyn Du Lighthouse

Also known as Penmon Lighthouse, Trwyn Du Lighthouse is located near to Puffin Island, and marks the channel between the island and Penmon Point.

A lighthouse was called for here following the wreck of the Rothsay Castle. The route was an important one, used by merchants sailing into and out of Liverpool.

Trwyn Du Lighthouse was built between 1835-38 and was the first wave-washed tower to be built by Trinity House Engineer James Walker.

Acetylene gas was introduced into Trwyn Du Lighthouse in 1922, making it the first Trinity House lighthouse to be automated.

In 1996 the lighthouse was converted to solar power.

The Lighthouse Keepers Cottages are also located nearby at Penmon Point. They were sold off in the summer of 1995 after being used previously for long term lets. They are now privately owned.
