In 784 the name “wazzarburuc” appeared for the first time in a document from the monastery of St. Gallen. In the 10th century, this island fortress served as a refuge for the monasteries of St. Gallen. It is believed that between 925 and 955 the Hungarians dared to attack the St. Gallen monastery fortress Wasserburg with fire and sword, but this was possibly repelled despite a fire on the foothills. Traces of the excavations carried out in 1993 indicate this.[7] This document mentions a church of Saint George, which belongs to the monastery of St. Gallen. Until 1280, the Lords of Kisslegg, as ministerials of the monastery, were responsible for the rule of Wasserburg, then the rule went to the Lords of Schellenberg for 500 silver marks. They expanded Wasserburg into a fortress as a St. Gallen fiefdom (until 1826).

Although lying on the (quiet) district road, it is a beautiful place with a view of the Schleinsee estate with the court chapel and the private Schleinsee. There are also benches above the farm near the water reservoir with a great view of Lake Schlein and Lake Constance, including the Säntis massif.
