Cardiff Bay Barrage

About

The Cardiff Bay Barrage (Welsh: Morglawdd Bae Caerdydd) is a monumental civil‑engineering achievement that spans the mouth of Cardiff Bay in Wales. Completed in 2001 and covering a length of 1.1 km, the barrage was designed to convert the once tidal bay into a permanent freshwater lake, thereby boosting flood defence, wildlife habitats, and the revitalisation of the surrounding docklands. The structure features five controlled spillways, a fish pass that allows salmon and other aquatic species to reach the River Taff, and a series of basins that offer unique opportunities for walking, cycling and wildlife observation. Its iconic bascule bridges and the surrounding promenade provide visitors with panoramic views of Cardiff city and the surrounding hills. Visitors benefit from the free public access to the barrage and can enjoy a safe, well‑lit pathway that links various marinas, yacht clubs and walking routes. The barrage is a focal point for local events, water‑sporting activities and ecological monitoring, making it a popular destination for families, history enthusiasts, and nature lovers alike.
