Burg Neuberg, Medieval castle in Hartberg Umgebung, Austria.

Burg Neuberg stands at 513 metres above sea level on the slopes of the Ringkogel above the village of Löffelbach, west of Hartberg. Its oldest part is a square bergfried about 36 metres high with the palas, whose lower section is Romanesque and dates from around 1160. The castle forms an irregular pentagon around a narrow, plain inner courtyard, and a three-storey cannon tower with the castle chapel on its ground floor stands by the outer gate.

Burg Neuberg was built in the 12th century by Gottschalk Schirling, from 1166 von Neitberg, a son of Wulfing von Stubenberg, as a border fortress against Hungarian armies; its name derives from Neitberg, meaning a defensive castle. When the Neitberg line died out, Emperor Frederick III seized the estate in 1483. In 1518 it passed as an imperial fief to the Herberstein family, who held it, apart from an interruption between 1603 and 1660 when it belonged to the Counts Saurau, into the second half of the 20th century and enlarged it in the Renaissance style after the Italian bastion system.

The castle maintains its status as a protected monument, representing the architectural and defensive practices of medieval Austrian construction methods.

The castle is privately owned, so visits are limited to the exterior; the inner courtyard and the chapel in the cannon tower cannot be entered. The complex stands at 513 metres above sea level west of Hartberg above the village of Löffelbach, with the outer gate, the three-storey cannon tower and the extended outer bailey reached on foot.

The castle is privately owned, so visits are limited to the exterior. Its name derives from Nitperg or Neitberg, meaning a defensive or battle fortress, reflecting its origin as a border stronghold against Hungarian forces.
