The beautiful baroque fountain was put into operation after years. The octagonal Venetian fountain by the Italian architect Giovanni Giacomo Tencalla from 1635 is decorated with cast iron swans. It is the last of the nine fountains in the castle park. The water from the Dyje, which gushed from it for several centuries, clogged the fountain itself with algae and dirt from the pipes. The fountain is now connected to filtered water to prevent these problems. Fountains are also functional.
