Enniscorthy Castle is an imposing Norman stronghold, which dates from 1205 and was a private dwelling until 1951. The castle was built by the DePrendergasts. In the early 1580s the poet Edmund Spenser leased the property that included the castle.
The castle was also once owned by Sir Henry Wallop. The castle was the site of many fierce battles during the Cromwellian years and also the 1798 Rising. The castle houses the Wexford County Museum, which contains extensive 1798 rebellion-related material, as well as items of local and agricultural interest.
