Climate
As Peter Dör-fler, the vicar of St. Ulrich, wrote in 1834: "Der See läßt im Winter bei großer Kält' unter dem Eis ein gewaltiges Pillen hören.." ("When it is very cold in winter, the lake makes great roaring noises below the ice.").
Coat of arms
The golden cross of St. Ulrich on the locality's coat of arms refers to Ulrich, bishop of Augsburg, honoured as a fighter against the "heathen hordes". He died in 973.
