It was built in 1613–19 by Markus Sittikus von Hohenems, Prince-Archbishop of Salzburg, and named for the "clear spring" that supplied it.
The schloss is also famous for its jeux d'eau (watergames) in the grounds, which are a popular tourist attraction in the summer months.
These games were conceived by Markus Sittikus, a man with a keen sense of humour, as a series of practical jokes to be performed on guests.
Other features are a mechanical, water-operated and music-playing theatre built in 1750 including some 200 automata showing various professions at work, a grotto and a crown being pushed up and down by a jet of water, symbolising the rise and fall of power.
At all of these there is always a spot which is never wet: that was where the Archbishop stood or sat, to which there is no water conduit and which is today occupied by the tour guide.
