Schloss Liesing, Protected castle in Liesing, Austria.

Schloss Liesing is a castle in Vienna that consists of multiple wings arranged around an inner courtyard. The buildings combine elements of a stately home with various rooms and structures organized around a central court.

The castle originated from a farm settlement first mentioned in 1387 and called Hausgraben. During the sieges of 1529 and 1683, the structure suffered considerable damage.

The early-Baroque wing now houses a municipal music school, while the late-Baroque wings hold 23 subsidised rental flats and a new annex by the moat adds 12 privately owned flats. The hazel branch with four nuts over flames and the year 1683 in Liesing's coat of arms recalls the legend that this tree alone survived the 1683 siege.

The grounds feature a public park area that visitors can explore and are easily reached by public transportation. The address Perchtoldsdorfer Straße 6 in Vienna's 23rd district helps with navigation to the property.

After the 1683 siege, a single hazel tree survived in the castle park and later became a symbol of the district. This tree was incorporated into Liesing's coat of arms and remains a reminder of the location's history.
