Lyssach is first mentioned in 894 as
Lihsacho and as
Lissacho in 1255. The oldest trace of a settlement is
Hallstatt grave mounds in the Birchiwald. The village is first mentioned in a donation document from 894 where a noble lady, Pirin, donated land in the village to the
Abbey of St. Gall. While the Abbey was a major landholder in the village, politically, religiously and socially it was part of the village of
Alchenflüh. Between the 13th and 15th centuries, the
Kyburgs and various monasteries acquired land in the village. In 1429 and 1481
Bern bought out many of the land holders. Following Bern's acceptance of the
Protestant Reformation in 1528, the remaining ecclesiastical properties were taken by Bern when the monasteries were secularized. Beginning in the 17th century, Lyssach,
Aefligen, Rüdtligen and
Ruti formed a school cooperative which built a schoolhouse in Rüdtligen. In 1775, Lyssach built their own schoolhouse, that they shared with Ruti until 1804. During the 18th century, the
chaussee or highway from Bern to
Zurich passed through the village. In 1857 a station and railroad further connected the village with the rest of the country. The population and economy expanded rapidly after 1965 when the
A1 motorway was built near the village. New housing developments, schools, sewers and a commercial zone were all built to handle the growing population. Lyssach has grown into a regional business and economic center. ==Geography==
