Lassee

The parish of Lassee was first mentioned in a document in 1115 and was also called Lauchsee (the lake where leeks grow) at the time. Schönfeld first appears in 1262 under the name Seeveld. From the oldest documents it can also be deduced that the sovereigns of Austria had significant possessions in and around Lassee. For example, the last Babenberg, Duke Frederick II the Warlike, also enjoyed tithes to Lauchsee in 1241. In 1724, Lassee was handed over to Duke Eugene of Savoy by Charles VI and assigned to the chancellery in Obersiebenbrunn. The village was granted market status in 1822.

The market coat of arms was awarded on February 15, 1977 and symbolically describes rural tradition and the parish's affiliation to Melk Abbey. The depicted horse stands for many years of cattle breeding. The golden ears of corn refer to the "granary of Austria". The crossed keys are the symbol of the Benedictines, to whom the parish of Lassee belongs.
