Corvin Castle, also known as Hunyadi Castle or Hunedoara Castle, is a Gothic-Renaissance castle in Hunedoara, in Romania. It is one of the largest castles in Europe and figures in a top of seven wonders of Romania Tourists are told that it was the place where Vlad III of Wallachia (commonly known as Vlad the Impaler) was held prisoner by John Hunyadi, Hungary's military leader and regent during the King's minority, for 7 years after Vlad was deposed in 1462. Later, Vlad III entered a political alliance with John Hunyadi, although the latter was responsible for the execution of his father, Vlad II Dracul. Because of these links, the Hunedora Castle is sometimes mentioned as a source of inspiration for Bram Stoker's Castle Dracula. In fact, Stoker neither knew about Vlad's alliance with Hunyadi, nor about Hunyadi's castle. Instead, Stoker's own handwritten research notes confirm that the novelist imagined the Castle Dracula to be situated on an empty top in the Transylvanian Călimani Mountains near the former border with Moldavia
