Canton of Schaffhausen
The water castle is located at the "Rheinfall", built on a small island in the Rhein river at the municipality of Neuhausen am Rheinfall in the Canton of Schaffhausen, opposite of the Laufen Castle in the canton of Zürich. The "Schlössli" (twee for German "Schloss", meaning castle) owes its name to the location on a small island, washed by the water of the Rheinfall, which used to be known as "Werd", meaning literally a river island.
