Dolmen de Guernévez dit Ty Saint-Dénès (Box D3 28, 31): by order of 27 December 1923
Origin and history
The Dolmen de Guernévez, also known as Ty Saint-Dénès, is a megalithic monument located in the commune of Saint-Goazec in Finistère. Daté du Neolithique, it illustrates the funeral and architectural practices of this prehistoric period in Brittany. This type of structure, composed of large erect stones, generally served as a collective burial and marked the landscape in a sustainable manner.
The site was officially recognized for its historical and archaeological importance, as evidenced by its classification as Historic Monuments by order of 27 December 1923. This classification protects the constituent elements of the dolmen, identified under cadastral references D3 28 and 31. Although the available sources do not specify the details of its construction or its specific use, its state of conservation and its approximate location (1 Guernevez Ar C.
The location of the dolmen, noted as "passable" (level 5/10) in the databases, suggests that its exact location may require additional verification. The available coordinates place it near Saint-Goazec, a rural town in the centre Finistère, where prehistoric remains are relatively frequent. These monuments, often linked to religious or social practices, offered Neolithic communities a place of remembrance and gathering, reflecting their organization and beliefs.
No information is available on the current accessibility of the site, its possible openness to the public, or related services such as guided tours. The data come mainly from the Merimée database and Monumentum, which list the French Historical Monuments without always detailing their contemporary use. The absence of complementary sources limits the precise knowledge of its history beyond its construction period and classification.
