The Ratzlburg is the ruin of a spur castle from Staufer times on a mountain spur near Oberrothenbuch ( Braunau am Inn ) and is located in the municipality of Überackern in Upper Austria . The lords of the castle belonged to the Rohr family .
history
The Ratzlburg was built in the 12th century. Heinrich von Rohr donated the Ratzlburg to the Ranshofen monastery as early as 1277 . From this point on, the plant was abandoned and served the population as a quarry for the extraction of building material; For example, the tower of the nearby Schwand parish church was built from stones from the Ratzlburg. The residential tower was uncovered and preserved in excavations carried out by the Upper Austrian state museums between 1992 and 1998.
description
The defining part of the castle is an octagonal residential tower from the Hohenstaufen era. It has cavities that have taken about 0.3 m wide tension beams, the wall thickness is 2.5 m. The walls are made in two-shell technology. The inner and outer shells are made of tufa , the space in between is filled with layers of large river pebbles in lime mortar. The lowest ring of tie bars lies on the foundation at the level of the original ground level. The tension beams are offset from the center of the wall to the outside and are crossed at the corners of the building so that they could distribute horizontal tensile and compressive forces over the entire circumference. Another drawbar ring is located two meters higher, which was indicated in the context of conservation by installing three pieces of joist. A wooden floor was installed inside the residential tower. The existence and altitude of such was archaeologically proven. A triangular extension connects to the southwest, which could have served as a staircase. A resting place for visitors with benches and a table has been set up to the northeast of the residential tower.
