Cologny (French pronunciation: [kɔlɔɲi]) is a municipality in the Canton of Geneva, Switzerland.

The Lake Geneva area was conquered by the Roman Republic in the 2nd century BC.

The Romans built a road from Corsier through the Cologny area to Frontenex during their centuries old rule of the region.

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.

By claiming Cologny or Colonia Allobrogum as the publication location, they were able to circumvent French laws which banned books from Geneva.

Beginning in the 18th century elegant chalets sprung up along the shores of Lake Geneva in Cologny.

Due to the poor weather, the guests spent days indoors telling each other horror stories.

Mary Shelley's Frankenstein and John Polidori's The Vampyre, the first modern vampire story, both resulted.
