Origin and history

The Kastell Lostmarc'h de Crozon is a monument located in the municipality of Crozon, Brittany. The available sources do not specify its exact nature or construction period, making it a site whose history remains to be clarified. Monuments of this type, often linked to defensive or residential functions, played a central role in the organisation of Breton territories.

In Crozon, as in other coastal areas, these structures could serve as monitoring points or refuges for local populations, in a context marked by agricultural, maritime and sometimes regional geopolitical tensions.
