Beauregard Castle

Château de Beauregard, built around 1250, was listed as a Historic Monument on June 1, 1964 (facades, roofs).
A private castle, only the park and gardens are open to visitors during the summer season.
It stands on a promontory, 25 meters above Lake Geneva. Its strategic position provided both protection and surveillance of the natural harbor formed by the Bay of Beauregard.

The stones used to build the Château came from the demolition of the Château de Rovorée, and form a wall one metre thick, two metres high and 110 metres long.
A pentagonal roof caps the keep, while a rounded corner tower completes the ensemble. In 1730, the Château courtyard was not yet open to the public, but the old fortifications and pits had already disappeared.

Like all castles, Beauregard occupies a strategic position. It enabled the Count of Geneva, on whom it depended, to control navigation on Lake Geneva. Beauregard was originally a military construction, an outpost.
From its sheltered harbor in the small gulf, galleys sailed to Versoix, loaded with wheat, wine and hay. Amédée VIII acquires the Genevois region
and Beauregard became part of the Chablais region.

A succession of owners followed. In 1670, Gaspard Costa bought the château. Since then, it has remained in the hands of the same Costa family. Damaged several times by the Bernese in 1536, and by the French Revolution in 1792, the building has undergone many transformations, but retains a magnificent pentagonal keep, currently topped by an impressive roof.
