The history of the castle began in 1760, when the then reigning Count von Öttingen- Soetern had a family seat built at the foot of the old Dagstuhl Castle.
Today, its venerable rooms are occupied by the Leibniz Centre for Computer Science. The enchanting garden of Dagstuhl Castle has been laid out according to the plans of Baroness Octavie de Lasalle. The so-called „Painter Countess“ has also left her mark on the Castle Chapel and with the Stations of the Cross in the crypt.
