The Old island of the Boating lake can be reached by a wooden bridge. There an amazing artwork can be seen. The hydraulic system is worth visiting mainly in the evening time. It was made by István Haraszty ordered by Dénes Deák art collector, patron.

The human fantasy and view are kept in motion by the babbling water. The more than 8 metre high, red copper, bronze, steel, chrome steel, glass, electronic and hydraulic equipment originally was called „Téráztató”-„Space Soaking”.
