Pustý hrad
Pustý hrad is the ruined medieval castle on a forested hill above the Hron river in the southern part of Zvolen, central Slovakia. The site covers a very large area and comprises an Upper Castle on the hilltop and a Lower Castle on the saddle below; substantial stone fortifications, two keeps and a palatial complex once stood there. Systematic excavations have revealed prehistoric and medieval phases and parts of the site have been partially reconstructed for visitors.

As it stood in 1330
The shape it held in its prime.
Perched on a wooded hill above the Hron, the castle in its prime filled a broad plateau with continuous grey-brown rubble-stone curtain walls, multiple rectangular towers and two prominent keeps on the highest point. The Upper and Lower Castle formed stepped terraces linked by a long defensive wall across the saddle. Entrance was through an arched gate set into a multi-storey gate tower; a northern palace block and terraced courtyard with a water tank sat in a panhandle of the stronghold. Rooflines and wooden floors completed the ensemble.
Its story
The story of Pustý hrad.
Pustý hrad — the "deserted castle", originally Zvolen Castle or Old Zvolen — covers 76,000 square metres above the river Hron, arguably one of the largest medieval castles in Europe. The hill drew settlers from the late Stone Age, and a Slavic castle was founded here in the 9th century; incorporated into the Kingdom of Hungary as the seat of Zólyom County, its oldest stone buildings — including the 12th-century keep, once 50 metres high — are attributed to King Béla III.
In the 13th century the royal stonemason master Bertold fortified an exceptionally large area to protect refugees from Zvolen in case of a Mongol invasion: Upper and Lower Castles ringed by massive fortifications, a 206-metre defence wall in the saddle, and a second keep of 20 by 20 metres — one of the largest residential buildings in Central Europe at the time. The castle is first mentioned in the chronicle Gesta Hungarorum at the beginning of the 13th century.
Later development came under counts Demetrius and Doncs of the Balassa family; Magister Doncs, a knight and diplomat serving Charles I of Hungary and influenced by a journey to France, extended the Lower Castle and ordered a Gothic modernisation — the works now known as Doncs' Castle. The castle lost importance in the 15th century amid the conflicts of John Hunyadi and John Jiskra of Brandýs, and was ruined by fire in a siege of 1452, probably burnt by Hunyadi's troops.
