The old
Penarth Dock closed in 1963. Some of its basins were earmarked to be filled with household refuse, while others were to be redeveloped for housing and a marina for leisure boats. It has a boatyard and over 300 berths for
yachts and small boats. In 1999 the construction of the
Cardiff Bay Barrage was completed, which meant Penarth Marina improving the safety of the marina environment facing
Cardiff Bay. Old
Victorian dock buildings, located between the marina and Cardiff Bay Barrage are being converted for leisure use. The Old Custom House on Dock Road has been converted into restaurants, El Puerto and La Marina. The adjacent Grade II-
listed Marine Buildings, built in 1865, were expected to be converted into a hotel ==References==
