South Stack Lighthouse was the first lighthouse to be built on Anglesey. At a cost of £12,000, in 1809 and was built on the summit of Ynys Lawd a small rocky Island which is situated on Holy Island, to the North West of Anglesey.

The first attempt to get a lighthouse built here was in 1665, King Charles I received a petition for a patent to erect a lighthouse, the patent was not granted and seafarers would have to wait several hundred years until 1809 when the very first light was used to highlight this dangerous part of Anglesey.

Trinity House surveyor and architect Daniel Alexander drew up the plans and in 1808 construction started, nine months later, and the South Stack Lighthouse was completed. The project was overseen by Captain Evans, who had been a determined campaigner for a lighthouse at this location.

Prior to 1828 the only access to the Lighthouse at Ynys Lawd was in a basket which was suspended on a hemp cable. From 1828 an iron suspension bridge was built which made life so much easier for stores and the Lighthouse keepers to get to Ynys Lawd.

In 1964 the suspension bridge was replaced, but in 1983 the bridge was closed to the public for safety reasons. In 1997 a new bridge was built out of aluminium and the iconic Lighthouse was reopened to the public.
