Alignements de Kerzérho, located in Erdeven (Département 56), is a historic monument. The monument is currently closed to visitors.
Second largest megalithic alignment in the world after Carnac, Kerzérho stretches nearly 2,000 standing stones across more than 2 km of Breton moorland. A granite silence inhabited by 5,000 years of history.
In the heart of the Pays d'Auray, between open moorland and pine forests, the Kerzérho alignments form one of the most impressive megalithic complexes in Europe. Erected by Neolithic populations whose sophistication still amazes us, these rows of standing stones stretch for more than two kilometres in the commune of Erdeven, forming ten parallel rows that originally numbered up to 2,000 menhirs, around 1,100 of which still stand today, with the largest reaching heights of over three metres. What sets Kerzérho apart from its illustrious neighbours at Carnac - classified as a world archaeological myth - is precisely its relative discretion. Less frequented, it offers a more intimate, almost contemplative experience. As you walk between the rows of granite, you can still feel something of the ritual power that these monuments must have inspired in their builders: the repetition of the motif, the perspective that fades into the horizon, the silence that is disturbed only by the Atlantic wind. The site is part of a vast megalithic complex that criss-crosses the Quiberon peninsula and the surrounding area. Kerzérho is not isolated: nearby are dolmens, tumuli and other remains that bear witness to dense and organised human occupation of the area over several millennia. The local granite stones, quarried and transported from nearby outcrops, come in a variety of shapes - ovoid, tapered, tabular - suggesting an aesthetic as much as a symbolic intent. The visit lends itself to a free, meditative wander. At dawn, when the morning mist envelops the menhirs in a low-angled golden light, the sight is breathtakingly beautiful. Photographers and archaeology enthusiasts will love it here, as will families looking for an authentic insight into Breton prehistory. Children, often fascinated by the size and mystery of these stones, develop a natural curiosity for ancient civilisations. Around the site, the typical Breton moorland unfurls its purple heather, golden gorse and wooded plots, making Kerzérho not only a first-rate archaeological monument, but also an exceptional natural area where human heritage and landscape merge into a single memorable picture.
The Kerzérho alignments consist of around 1,100 standing menhirs out of an original estimate of some 2,000, arranged in ten parallel rows stretching for more than two kilometres in a north-west/south-east direction. The menhirs are carved from local granite, a rock that is abundant in the Armorican subsoil, with hues ranging from bluish-grey to pale pink depending on its mineralogical composition. Their height varies considerably: the smallest are barely 0.80 metres high, while the largest reach over 3.5 metres above ground, suggesting an intentional hierarchy in the positioning of the blocks. The morphology of the stones is remarkably varied: some are ovoid in cross-section and have the tapered profile characteristic of Carnacan menhirs, while others are more squat and tabular. To date, no inscriptions or ornamentation have been identified on the Kerzérho menhirs, unlike some contemporary monuments in the region, which feature intaglio carvings (axes, crescents, wavy lines). The apparent austerity of the stones reinforces the effect of mass and repetition that is the very essence of the alignment. The general orientation of the site - with a slight fan-shaped divergence to the west, similar to that seen at Carnac - bears witness to genuine topographical and perhaps astronomical mastery. The whole site is set in a gently undulating moorland landscape, which accentuates the effects of perspective and gives the impression that the rows of stones extend into infinity. A few large, isolated menhirs, located on the periphery of the main alignment, could mark out landmarks or ritual boundaries for the ensemble.
