Stacen y Brenhin

Stacen y Brenhin, also known as St. Catherine's Island, is a small tidal island located off the coast of Tenby, Pembrokeshire, in Wales. The island is situated approximately 200 meters from the mainland and can be reached by a causeway during low tide.

The island is home to a historic fortification, which was built in the mid-19th century as part of the defense system against French invasion. The fort, constructed from local limestone, consists of a central tower surrounded by a defensive wall and a moat. It was later used as a private residence before being abandoned in the early 20th century.

Stacen y Brenhin is known for its picturesque and rugged landscape, with rocky cliffs and a small sandy beach. The island is a popular destination for tourists and locals alike, offering stunning views of the surrounding coastline and the town of Tenby.

Visitors are able to explore the island and its fortification, although access is limited to low tide periods due to the causeway being submerged during high tide. The fort is not fully open to the public but can be viewed from the outside.

The island is also a designated Site of Special Scientific Interest (SSSI) due to its rich biodiversity. It provides a habitat for various species of plants, birds, and marine life, making it a haven for nature enthusiasts.

Stacen y Brenhin is a unique and historically significant location, combining natural beauty with a glimpse into Wales' military past.
