Cologny

The oldest trace of a settlement in the area is a Neolithic lake side village which was discovered near the village of La Belotte. The Lake Geneva area was conquered by the Romans in the 2nd century. They built a road from Corsier through the Cologny area to Frontenex during their 2 centuries of residency.
During the Middle Ages, it was part of the lands of the Counts of Geneva, before it was acquired by the Bishopric of Geneva. The village church of Saint Peter was placed under the parish of Vandœuvres in 1406, indicating that it was probably built before the 15th century. In 1536, Cologny joined the new faith of the Protestant Reformation as nearby Geneva became a center of reform. Two years later, in May 1538 a treaty between Bern and Geneva placed Cologny in the city of Geneva.
