Corvin Castle, also known as Corvins' Castle, Hunyad Castle or Hunedoara Castle (Romanian). Corvin Castle was laid out in 1446, when construction began at the orders of John Hunyadi who wanted to transform the former keep built by Charles I of Hungary. Castle represents one of the most amazing and well-preserved medieval buildings, being in fact the most famous property of John Hunyadi, building that even today dominates the city of Hunedoara.
