Huniade Castle stands at the eastern end of Victory Square, a heavy stone-and-brick fortress block surrounded by lawns and the modern boulevard. It is the oldest building in the city, dating in its core to 1308 under King Charles I of Hungary and rebuilt by John Hunyadi (Iancu de Hunedoara) in the 1440s. The Habsburgs adapted it as a barracks and arsenal after 1716 and it has been a museum since 1947.
The castle houses the National Museum of Banat, with extensive collections of regional archaeology, history and natural sciences. A long-running restoration that began in 2016 has reopened sections in stages. The exterior is best seen from the small park immediately south, where the medieval and Habsburg-era walls layer visibly against each other.
