The Upper Castle, also known as Oberes Schloss, is a majestic medieval fortress crowning the summit of Siegberg hill in the city of Siegen. A site that Germany is rightfully proud of, it is a unique historical complex situated 307 meters above sea level.

Today, the castle walls house the famous Siegerland Museum (Siegerlandmuseum). Here, visitors can explore the rich history, culture, and folklore of the region. The complex includes the main historical buildings, a cozy inner courtyard featuring a fountain preserved from the 13th century, and a picturesque park surrounding the fortress walls.
The castle is not only an architectural monument but also an important cultural hub where ancient stone vaults meet art and science. It is a must-visit for anyone wishing to connect with the heritage of the County of Nassau and see how the German aristocracy lived in centuries past.
