A Breton woman in traditional black dress and white lace coiffe stands serenely amid massive tumbled megaliths at Kertugal, near Saint-Quay — her presence giving human scale to the ancient druidic sanctuary and grounding the prehistoric in the living present of rural Brittany. This sepia photographic card, numbered 7040 in E. Hamonic's celebrated Monuments Mégalithiques de Bretagne series, documents a megalithic site that was already drawing curious visitors in the early 1900s. The caption labels it a "Sanctuaire druidique," reflecting the era's romantic association of Breton megaliths with Celtic druids — a framing that, while archaeologically imprecise, powered an enormous tourist and postcard industry. The woman's traditional costume, worn here as everyday dress rather than performance, anchors the image in authentic Breton rural life circa 1900–1910. The back is undivided — or shows the early Hamonic divided format — with no postal use. Hamonic's megalithic series is among the most systematically documented photographic surveys of Breton prehistoric monuments ever undertaken, making these cards genuine historical records.
