Schloss Kaiserebersdorf

Schloss Kaiserebersdorf is a Renaissance castle in Simmering with thick stone walls, a circular keep, and multiple levels arranged in a triangular footprint. The fortress combines strong defensive structures with residential spaces designed for noble occupants.

The castle originated in the 12th century and became imperial property in 1499 under Maximilian I, who redesigned it as a hunting residence. Over time it evolved from a medieval fortress into a Renaissance palace for royal use.

The structure shows how medieval defensive design mixed with Renaissance elegance, featuring stone walls built for protection alongside rooms designed for comfortable living. Walking through it, you notice how both military and domestic purposes shaped its layout.

The site currently operates as a prison facility and is typically closed to visitors since it functions as an active correctional institution. Those interested in the exterior architecture can view it from the surrounding streets.

In 1552, an early menagerie was established here under Maximilian II, housing exotic animals for the imperial family. This animal collection later moved and became the foundation for what would develop into Schönbrunn Zoo.
