History
Burg Obernberg is a medieval hilltop castle in Obernberg am Inn, Austria, associated with the Counts of Formbach and probably originating in the eleventh century. The earliest date linked to it is 1092. Its position above the Inn gave the stronghold a strategic role, while its later history connected it with the Counts of Andechs and the Diocese of Passau.
Formbach origins and Passau control
The Counts of Formbach and their successors, the Counts of Andechs, held Obernberg until the castle was ceded to the Diocese of Passau around 1191. The diocese was an ecclesiastical territory centered on Passau that also exercised secular lordship over properties such as Obernberg. Between 1199 and 1202, Bishop Wolfker greatly enlarged the earlier fortification.
Meginhart de Obernberge appears in 1160 as the castle’s lord and burgrave. A burgrave was a castle governor responsible for administration and defense. His title reflects the importance of Obernberg as both a military stronghold and a center of local authority.
Sieges and changing lordship
Conflict repeatedly altered control of the castle in the thirteenth century. In 1241, the Muhringer of Eberschwang attacked Obernberg and its market. Duke Frederick II of Austria captured the castle in 1243 after a siege aided by the treachery of the burgrave charged with defending it. He then entrusted its custody to Counts Ulrich and Wernhart von Schaunberg.
The Schaunbergs resisted a siege in 1245 by Bishop Rüdiger of Passau, who was allied with Duke Otto of Bavaria. In 1246, Duke Frederick returned Obernberg to the Diocese of Passau. Duke Otto occupied it for a time, but it reverted to Passau under Bishop Otto of Lonsdorf.
The castle and its associated territory remained under Passau until the early nineteenth century, although the diocese repeatedly leased or pledged them. Obernberg was pledged to Bavaria in 1368, to the Archdiocese of Salzburg for four years after an attack in 1372, to Duke Albert III in 1388, and to Count Ezzelin of Ortenburg in 1411. A toll was introduced in 1466 by the official administering the settlement and castle. A major fire damaged Obernberg in the late fourteenth century, after which the complex was repaired.
Administrative and judicial transformation
Obernberg’s military importance gradually declined toward the end of the sixteenth century. In 1550, Bishop Count Wolfgang of Salm commissioned a new residential and administrative building for the local official responsible for managing the castle. That building later served as a court for more than two centuries.
Bavarian troops occupied Obernberg during the War of the Spanish Succession, a European conflict over the Habsburg succession, in 1701. Rebels seized the market during the peasant uprising of 1705. In 1782, Obernberg came under Austria, while the Diocese of Passau remained the feudal landholder rather than the territorial sovereign.
Secularization, the transfer of church lands and political authority to secular governments, ended Passau’s territorial rule over Obernberg in 1803. The castle and neighboring territories passed to the Austrian imperial government, which established a land court there. In 1848, the former land court became a circuit court, followed by its conversion into a district court in 1850.
Demolition and modern use
The complex suffered extensive loss in the nineteenth century. In 1807, several buildings were altered or demolished, including the surviving medieval keep, the principal defensive tower of the castle. Napoleonic occupying forces demolished the remaining defensive structures in 1809, leaving two principal historic buildings.
In the modern period, one of these buildings houses the district court and the other houses the Kunsthaus Obernberg, a cultural meeting place and museum facility. The castle area belongs to Upper Austria and is protected as an Austrian monument.
Remains
Burg Obernberg stands in a park on a terrace at the edge of Obernberg am Inn’s historic center, on ground that falls steeply toward the Inn. The former fortification was separated from the town by deep ditches on three sides, while a building occupied the fourth. Two independent buildings, sections of the surrounding ring wall, round towers, a postern, and a deep well survive within the grounds.
Walls and defensive remains
Ring wall and towers
Sections of the former ring wall remain, with a postern, or small secondary gate, set into the surviving masonry. Round towers survive on the northern and western sides. The large tower, the eastern and southern walls, the gate tower, and the drawbridge were demolished. The former neck ditch was filled with demolition material, leaving two shallow depressions visible in the grounds.
Well shaft
A surviving well shaft descends more than 60 metres, with one measurement giving its depth as 63 metres. It is completely lined with tuff, a relatively soft porous stone formed from consolidated volcanic ash. The shaft has been restored and visually integrated into the castle grounds.
Surviving buildings
Administrative and court building
The building commissioned in 1550 is a long, single-storey structure with a tall stepped gable. Above its main entrance is a large stone inscription bearing the arms of the Diocese of Passau and the words “1550. Dominus videbit. W. E. P. C. A. SALM,” identifying Wolfgang, Bishop of Passau and Count of Salm. Its original residential and administrative purpose was followed by more than two centuries of use as a court.
Cross-wing building
The isolated cross-wing is built from exposed tuff blocks. Although its present appearance is more recent, its substance is older. It formerly served as a tithe house, granary, or silo and was converted into an official residence in 1912. The building now accommodates the Kunsthaus Obernberg and functions as a cultural meeting place and museum facility.
Present grounds
A lawn now occupies the space between the two surviving buildings, covering part of the former strongly fortified character of the complex. A promenade known as the Bishop Wolfker Way once ran around the buildings with views toward the Inn. After a landslide and later overgrowth, only the right-hand path toward the Mautnerstiege remained walkable.
