Liechtenstein Castle and Kalenderberg

Liechtenstein Castle (Burg Liechtenstein = Light stone castle) is situated near Maria Enzersdorf in Lower Austria, bordering Vienna. It is on the edge of the Wienerwald (Vienna Woods). The castle, originally built during the 12th century, was destroyed by the Ottomans in the siege of Vienna in 1529, and again in the Battle of Vienna in 1683, and remained in ruins until 1884, when it was rebuilt.
