Hunyad Castle (Corvin Castle) is a medieval fortress located in Hunedoara, Romania. Often called "the king of castles" by Mikszáth Kálmán, it is one of the most spectacular Gothic-style castles.

The Citadel in Cluj-Napoca is a fortress situated on a 405-meter-high hill originally called Kőmál, next to the Little Someș River (Kis-Szamos).

One of the largest castles in Transylvania and the Székely Land covers an area of more than four hectares.

Construction of the Mikó Castle began in the spring of 1623 and was completed in the 1630s.
The Bánffy Castle of Gilău is one of Transylvania’s most important Renaissance monuments, once the residence of the Rákóczi and Bánffy families, now being restored as a cultural center near Cluj.

Perched atop a 150-meter-high hill, Râșnov Fortress provided protection to the local population with varying success. It was equipped with a watchtower and a small permanent garrison.

In the 1450s, the fortress came under the ownership of Mihály Szilágyi and later John Hunyadi, remaining in the Hunyadi family until the death of John Corvinus.

The first reliable written record of Făgăraș Fortress dates back to 1456.
