Schloss Sonnberg, Renaissance castle in Hollabrunn, Austria.
The four-winged stone structure stands near the Göllersbach stream, featuring Renaissance architecture with a central courtyard and defensive water elements.
The original fortress dates from 1177, when it belonged to the Sunnenberg family who controlled regional trade routes toward Bohemia and Moravia.
The castle transformation from a medieval stronghold to a Renaissance residence reflects architectural changes in Austrian noble residences during the 16th century.
The castle now functions as an administrative building for the Sonnberg Penal Institution, which accommodates up to 350 inmates in modern facilities.
During World War II, Princess Ileana of Romania converted the castle into a hospital for Romanian soldiers before Russian forces occupied the building.
