Glerula or …Saint-Saphorin is a municipality in the Swiss canton of Vaud, located on the shore of Lake Geneva, in the district of Lavaux-Oron. 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.
