The Castle Alt-Landsberg is the ruins of a hilltop castle in the area of today's community Bauma in the canton of Zurich in Switzerland . It is located on a hill above the Töss at 721  m above sea level. M.


Access was made difficult on the mountain side by an artificially deepened neck ditch . Today's access is from the south. After a first gate you came to a kennel and a drawbridge to a second gate to a staircase carved into the rock, which led directly into the complex.

The complex consists of a 25-meter-long western section and a slightly longer and wider eastern section, in which the residential buildings were located. The construction took place in several phases. An older complex, presumably with clapboard-roofed wooden houses, was expanded around 1200; the curtain wall was also built around this time. The old entrance in the north was replaced by a gate system in the southwest. A striking amount of tufa was used as building material . The spacious palace , which occupied the whole eastern part, was created in a later expansion phase. On the mountain side it was protected by a partially preserved three meter thick shield wall . The pillars that supported the first floor can still be seen. The transverse wall to the west and 14 meters deep Sodbrunnen being added later. It is conceivable that this narrow part formed a stairwell. No traces of a keep were found.

The complex of old Landsberg with perimeter wall , gate construction , kennel , patio, spacious palace and farm buildings represented a typical castle of the late Middle Ages . The castle complex was uncovered and restored in the 1960s.


The Alt-Landenberg Castle, from Old High German Landinberg ("Burg des Lando"), was built around 1200 as a typical clearing castle. Its beginnings and first residents are not documented. In 1315, however, the last knights of the castle, Rudolf and his son Pantaleon, fell in the Battle of Morgarten when they suffered a devastating defeat against the Confederates on the side of the Habsburgs . The castle then fell back to the monastery of St. Gallen as an inheritance , passed into the hands of different owners and in 1549 came to the city ​​of Zurich , which lent it on. The last owner mentioned is Hans Rüegg von Altlandenberg, who in 1651 offered to contribute stones from the increasingly decaying castle for a church. The castle ruins were uncovered and restored in 1958/63.
