Origin and history
The Gallo-Roman Trouguer site, located at the north-west end of Cléden-Cap-Sizun, is at the intersection of two ancient Roman ways: one connecting Douarnenez, the other leading to the bay of the Trepassés. The excavations revealed a quadrilateral of 120 meters on the side, of which today there is only a section of wall of ten meters, built in small cubic apparatus agglomerated with very hard cement. The objects discovered, such as weapons, ceramics, coins, glasses and bronze statuettes, suggest an important occupation. Among these artifacts, a naked man statuette holding a scepter and a duck could represent a local divinity.
The interpretation of the site varies according to the experts: some see it as a castrum of the Lower Empire, due to the presence of weapons, while others lean for a Gallo-Roman sanctuary. The remains, mentioned in the 16th century by Canon Moreau, have been gradually degraded. The walls, six metres high in the 16th century, were more than two in 1810 and only one metre tall during the excavations of the 1950s, probably due to local agricultural activities. In 1977, a portion of the walls could be photographed, but by 2020, vegetation had covered the site, making any observation difficult.
The site was protected by an order of 12 May 2000, covering both upland and upland remains and surrounding parcels. Although the property is shared between individuals and the municipality, its current state and accessibility remain limited by the lack of visibility of the structures and the regrowth of vegetation. Archaeological discoveries and historical descriptions make this a rare testimony of Gallo-Roman occupation in Brittany, although its exact use (military, religious or other) continues to cause debate among specialists.
