The uniqueness of the monument in Hunedoara consists in the representativeness of the military 15^th century architecture in southeastern Europe. The most developed civil architectural elements are here combined. The Western Palace is built following a French model. This is an unique space in the Hungarian kingdom and it shows the greatness and the social and financial power of the Corvin family. The 17^th century constructions are other elements that transform the castle into a singular one. Also the restoration woks in the 19^th century, together with all the other works named so far, offer to the visitor a mixture of architectural elements that belong to the gothic, Renaissance, baroque and neogothic styles.
