Corvin Castle was laid out in 1446, when construction began at the orders of John Hunyadi (Hungarian: Hunyadi János, Romanian: Iancu or Ioan de Hunedoara) who wanted to transform the former keep built by Charles I of Hungary. The castle was originally given to John Hunyadi’s father, Voyk (Vajk, Voicu), by Sigismund, king of Hungary, as severance in 1409.
It was also in 1446 when John Hunyadi was elected as the regent-governor of the Kingdom of Hungary by the Diet.
It was built mainly in Gothic style, but has Renaissance architectural elements. It features tall and strong defence towers, an interior yard and a drawbridge.
As one of the most important properties of John Hunyadi, the castle was transformed during his reign. It became a sumptuous home, not only a strategically enforced point. With the passing of the years, the masters of the castle had modified its look, adding towers, halls and guest rooms.
