Saarbrücken Castle, also known as "Saarbrücker Schloss", is a baroque castle in the Saarland state capital of Saarbrücken. It is located in the Alt-Saarbrücken district on the left bank of the Saar. Previous buildings on the site were a medieval castle and a Renaissance palace. Today, the castle serves as the administrative headquarters of the Saarbrücken Regional Association. The vaulted cellar and an extension house the exhibition rooms of the Saar Historical Museum. Parts of the castle complex with the casemates were uncovered under the castle square. Following extensive excavations between 2003 and 2007, the casemates are now accessible to visitors from the Historical Museum.
Since Saarbrücken Castle became the most important sight in the city of Saarbrücken alongside the Ludwigskirche church, the people of Saarbrücken have not only been able to take their guests to the castle square on Sundays, but also celebrate their festivities in the castle and its garden.
