Hellsau

The earliest trace of a settlement at Hellsau is an early medieval cemetery near the Äbi farm house. It is likely that the old village church once stood near the cemetery. The church was first mentioned in 1275 as a filial church of Burgdorf. It became a full church in 1353 under the patronage of St. Mary. It became part of the parish of Koppigen in 1422 and was given a chaplain in 1471. Following the Protestant Reformation the church was abandoned and eventually demolished.
For most of Hellsau's history, it was a village under the jurisdiction and town council of Koppigen. In 1571, Koppigen passed a law mandating fences in the Büeltscherzelg field because the farmers of Hellsau had been sneaking into the field to graze their animals. Agriculture is still important in the village economy, though a construction company provides a number of jobs. Between 1894 and 1911 it was the home of a private asylum and hospital. Marshes and meadows were drained in 1943-48. Starting in the 1820s Höchstetten and Hellsau formed a school district. The Moos school house was built in 1976.
