Welsh castles are known for their grandeur, and Harlech Castle is no exception. Towering over the glorious beach, Harlech Castle sits dramatically on a rocky crag with the mountains of Snowdonia as its impressive backdrop. This medieval castle was built by Edward I and has weathered centuries of battles, including the War of the Roses. There is no greater place to explore Welsh history than inside the walls of this imposing UNESCO world heritage site. The alternative Welsh national anthem, Men of Harlech, comes from tales of sieges and wars in Harlech. It’s no wonder it is one of the most popular castles to visit in Wales.
