Glérolles Castle

Glérolles Castle is situated in the municipality of Saint-Saphorin, canton of Vaud, Switzerland, on the northern shore of Lake Geneva. Its earliest elements date from a fortress built around 1150. The modern building serves as the headquarters for a vineyard of the same name, and as a venue which can be hired to host social events. It is a Swiss Cultural Property of Regional Significance.

Glerula or Calarona was a Gallo-Roman village. The chroniclers Gregory of Tours and Marius of Avenches described what is now called the Tauredunum event of 563. A landslip into the eastern end of Lake Geneva caused a tsunami which swept along the lake causing immense damage. Glerula was among the villages which were destroyed. It was never rebuilt. Instead, a new community was founded a short distance to the east, taking its name from the new church there, dedicated to Saint-Symphorien. That name has, with the passage of years, transformed into Saint-Saphorin.
