Parcel containing remains of a Gallo-Roman building (Box S 255): classification by order of 21 May 1976
Origin and history
The site of Guer, in Morbihan, houses a plot containing the remains of a Gallo-Roman building. Ranked a Historical Monument by order of 21 May 1976, this place illustrates the ancient occupation of the Breton region. The architectural traces, though fragmentary, attest to a Roman presence in this territory, now integrated into the municipality of Guer (code Insee 56075).
The precise location of the site, noted as "passable" (level 5/10), is located near Saint-Étienne, according to the GPS coordinates available. Communal property, this protected parcel (cadastre S 255) does not offer detailed information on its accessibility or current vocation (visit, services). Its classification reflects the heritage importance of the remains, typical of the Gallo-Roman civil or religious buildings in Armorica.
In the Gallo-Roman era, Brittany (then part of Gaul) was marked by progressive Romanization, with public, religious or domestic buildings scattered. These remains, often discovered by chance, reveal local practices combining Celtic traditions and Roman influences. Their preservation allows us to study the social and territorial organization of this pivotal period, although local written sources remain rare for Guer.
Available data from Monumentum and the Merimée archives highlight the archaeological interest of the site without specifying its original function (village, temple, workshop). The absence of recent excavations or detailed publications limited the understanding of its role in the Gallo-Roman Breton network, dominated by cities such as Vannes and Rennes at the time.
