Church and Fort St. Kibi
Saint Cybi was the son of a 6th-century ruler of Cornwall. He became a priest and settled in North Wales, where the King of Gwynedd granted him an old Roman military naval fortress to establish a religious community. Over time, the fort became known as Cybi Fort, and the island itself came to be called Cybi Island. The remains of the 4th-century Roman walls can still be seen today. They surround a beautiful Gothic church, which was built much later, in the 13th century. The church captivates visitors with excellent medieval murals and beautiful stained-glass windows.
South Stack Lighthouse
The idea of installing a lighthouse on the South Stack was officially put forward in 1665, when a petition was submitted to Charles II requesting a patent for such construction. The petition was not granted, and the building of the lighthouse was postponed by one and a half centuries. Only in August 1808, after navigation between Wales and Ireland increased - aided by the signing of the Act of Union of Great Britain and Ireland - the British engineer Daniel Alexander began construction work on the island. Within a year the lighthouse was ready and it was opened on 9 February 1809. In 1854 a fog bell was installed on the island, and in 1938 the lighthouse was electrified. In 1984 the station was transferred to automatic operation, and on 12 September the lighthouse keeper was removed from the island.
