Origin and history

The Menhir de Porzic is an iconic megalithic monument located in the commune of Old Bourg, Brittany. Built during the Neolithic period, it reflects the cultural and religious practices of prehistoric societies in the region. This porphyroid granite block, of fusiform shape and measuring 6 meters in height, was positioned on a height close to granitic chaos, highlighting its sacred or symbolic character for the local communities of the time.

Ranked as historic monuments on October 18, 1965, the Porzic Menhir enjoys heritage protection that recognizes its archaeological and historical importance. Its precise location, near the so-called Kerdalmez, as well as its imposing dimensions (2.70 m wide and 1.75 m thick), make it a remarkable example of the megaliths of the borough of Saint-Brieuc. The studies, like those conducted by Loïc Langouët, cite him as one of the notable megalithic sites of the Côtes-d.

The menhir is part of a wider landscape of Breton megalithic sites, reflecting a monumental construction tradition linked to the beliefs and social organization of the Neolithic. Although the sources do not specify its exact use (ritual, funeral, or astronomical), its presence attests to the ancient human occupation and technical mastery of the builders of the time. Today, there remains a point of interest for researchers and local history enthusiasts, accessible in a preserved natural setting.
