Rich in wildlife, steeped in history.
Just 5 miles from Cardiff and Barry, the tiny island of Flat Holm is a different world with a wealth of history and wildlife. You will be amazed at how much there is to discover.
Since the Dark Ages, Flat Holm has been a retreat for monks and since then has acted as a sanctuary for Vikings, Anglo-Saxons, silver miners, smugglers and cholera victims. Fortified in Victorian times and again in World War II it is perhaps most famous for receiving the first ever radio message across water by Marconi in 1897.
