Osterland Castle

Osterland Castle near Oschatz was probably a late Romanesque-early Gothic hunting lodge, built between 1211 (dendro) and 1230 under Margrave Dietrich the Oppressed, and already fell into disrepair from 1300 onwards as it no longer had a clear purpose. The three-story, four-wing complex was built over a stream and had the form of a Roman porticus villa with corner risalits. The spring or water house in the inner courtyard, temporarily uncovered during excavations in 1901–08 and 1991–92, is one of the most beautiful examples of European Romanesque architecture. A connection of this complex as a residence for the Margraves of Meissen and the Ostmark with the most important medieval court in the Margraviate of Meissen, the Thingplatz at the 1000-year-old court linden tree in nearby Collm, where 15 court days, known as Landthing, were demonstrably held between 1185 and 1259, and which continued in Oschatz until the 14th century, is plausible. A feudal letter for Wolfgang von Schleinitz from 1501 documents meadows, ponds, dams, and woods in the immediate vicinity of the object then called "Altes Steinhaus" (Old Stone House), which in 1501 belonged to the feudal possession of the Vogtshaus Oschatz, built around 1200, opposite the Oschatz town church. Another enigmatic object like Osterland Castle is the origin of Grillenburg Castle in the Tharandt Forest.
