I've spend a few days in Kassel, visiting the 'documenta 14' - and my host recommended to visit also the amazing water features. They start every year from 1st may until 3rd october, each wednesday and saturday, at the Unesco World Heritage Site 'Bergpark Wilhelmshöhe' between the palace and the Hercules monument.
I parked my car on one of the lower parkgrounds and took the bus up to the top of the hill, where the huge monument of Hercules is perched on top of the stone Octagonbuilding, completed 300 years ago in 1717.
Unfortunately there are construction works until 2018 on the Hercules and as well on the stages where the water cascades down, therefore on some of the photos also some scaffolds will be seen.
The waterfeatures start always at 2.30pm at the feet of the Hercules monument.
The visitors are following the water down to the big lake of the palace Wilhelmshöhe, where a fountain of about 50 meters ends the spectacle. Every time about 350.000 liters (92,000 gallons) of water are needed.
In the beginning the water flows from the Giant's Head basin down the Grand Cascades.
After the water reached the basin at the end of the grand cascades, it runs down to the Steinhöfer's waterfall, from there to the devil's bridge,
until it tumbles down the aqueduct,
before finally arriving at the lake of the palace, where the waterfeatures end in the fountain.
This whole system relies on natural pressure from reservoirs and underground pipes whose locks are opened manually. This system has been in place for more than 300 years.
The whole spectacle takes around one hour and 15 minutes, the way downwards is around 2.3 kilometres.
