The fortress is constructed on a neck of a dormant volcanic crater composed of andesite.
The 1849 explosion that destroyed the upper courtyard was caused by a fire in the powder magazine during the Hungarian Revolution.
In 1550, the fortress served as a temporary prison for the Transylvanian ruler Francisc Kendi.
The site includes three distinct enclosures protected by defensive walls and gatehouses.
The cable car operating to the fortress is one of the few inclined elevators in Romania specifically designed to reach a mountain peak site.
The Fortress of Deva is a 13th-century citadel perched on a volcanic cone overlooking the Mureș River valley. Its strategic position at the entrance of the Mureș Gorge made it a key defensive fortification for the Transylvanian region. The structure occupies the site of an earlier Dacian settlement known as Decidava. Throughout its history, the fortress served as a royal residence and a military stronghold for the Kingdom of Hungary and later the Principality of Transylvania. It was significantly expanded in the 16th and 17th centuries with bastions and defensive walls. A major explosion in the powder magazine destroyed much of the upper fortification in 1849. Today, the site features restored curtain walls, bastions, and the remains of the interior residential quarters. Visitors reach the summit via a combination of a cable car system and walking paths.
