Origin and history

The Lievrin Cave is a rock shelter located in the municipality of Brégnier-Cordon, in the department of Ain. This prehistoric site is distinguished by its semicircular shape, measuring about seven metres in length and width. Unlike a classic cave, it is a sheltered terrace without deep excavation, offering a protected natural space.

Archaeological surveys conducted in the upper part of the site revealed the presence of bronze-age pottery, attesting to an ancient human occupation. These findings highlight the importance of the site as a habitat or area of activity for prehistoric populations in the region.

The Lievrin cave enjoys double protection in respect of historical monuments: a first classification dates back to 13 June 1913, supplemented by a decree of 15 December 2011 which extends the protection to the entire shelter and its entrance slope. These measures are intended to preserve the archaeological remains and geological structure of the site.

The monument is now owned by the municipality of Brégnier-Cordon. Although the information on its accessibility to the public is limited, its location in Bugey, a region marked by a rich prehistoric and speleological heritage, makes it a site of interest to researchers and archaeology enthusiasts.

The accuracy of its geographic location is estimated to be poor (level 5 out of 10), which may complicate its exact identification on the ground. The coordinates available in the Merimée database and the approximate GPS data place the site near La Bruyere, on the communal territory.

This type of rock shelter was probably used by prehistoric communities as a temporary or permanent place of life, sheltering domestic or artisanal activities. In the regional context of the Bronze Age, these sites played a key role in habitat and population movements networks, often linked to the exploitation of local natural resources.
