Three palaces, linked by charming gardens rich in roses - high above the River Saale towers the former summer residence of the Grand Dukes of Saxe-Weimar-Eisenach. The Old Palace was built in the 16th century to replace a medieval fortress. The centrally positioned Rococo Palace was built around 1740, a summer home with apartments and two halls, adapted to stand on the terraced slope. The Renaissance Palace was purchased in 1824. Goethe stayed here for some weeks in the late summer of 1828, when he withdrew from society after the death of Grand Duke Carl August from Weimar.
In August every year, the Dornburg Night of the Castles is held in the castle gardens.
