Corvin Castle in Romania

Corvin Castle, otherwise called Hunyadi Castle or Hunedoara Castle, is a Gothic-Renaissance manor in Hunedoara, Romania. It is one of the biggest palaces in Europe and figures in a top of seven marvels of Romania. 

Corvin Castle was laid out in 1446, when development started at the requests of John Hunyadi who needed to change the previous keep worked by Charles I of Hungary. The mansion was initially given to John Hunyadi's dad, Voyk, by Sigismund, lord of Hungary, as severance in 1409.
