Origin and history

The Gallo-Roman villa of Plassac is a collection of archaeological remains attesting to a Roman occupation between the 1st and the 5th century AD. These remains, discovered near the present site of the church and the Gironde, reveal the existence of three distinct villas, typical of Gallo-Roman rural settlements. Their location near the estuary suggests an activity related to river trade and agriculture, characteristic of the aristocratic domains of the time.

Plassac, known as the Latin Blacciacum, shows a continuous disoccupation from antiquity to the Middle Ages. In the early Middle Ages, the village's activity centre moved to the heights overlooking the river, as evidenced by the discovery of a treasure of Merovingian coins in the 19th century. Gallo-Roman villas, partially excavated, are now protected as a historical monument, with plots classified in 1975 and others listed in 2024.

The archaeological site is integrated into the local landscape, where wine-growing activity (AOC Côtes-de-blaye) and proximity to the estuary shaped the economic history of Plassac. The remains, visible at the museum of the site, offer a light on rural life and trade in Roman Aquitaine, between the Upper Empire and the Lower Empire. Their preservation illustrates the heritage importance of Gallo-Roman traces in South-West France.

The church of Saint Peter, rebuilt in 1883, is partially built on the location of one of the villas, highlighting the superposition of the epochs. The bas-Plassac, around the harbour, experienced intense maritime activity in the 17th–18th centuries, before its decline in the 20th century. This contrast between ancient heritage and modern port dynamics characterizes the historical identity of the municipality.
