Seven Saints chapel, Pilgrimage chapel and dolmen in Le Vieux-Marché, France

The Seven Saints Chapel is a pilgrimage chapel from the early 18th century in the village of Le Vieux-Marché, Brittany, perched on a hillside above the Léguer valley. It has a Latin cross floor plan, a small bell tower, and is enclosed within a stone precinct.

The chapel was built between 1704 and 1714 near Plouaret, south of Lannion, replacing an earlier place of worship raised on the remains of a covered alley grave (allée couverte). That megalithic chamber, about 4.4 m long and 2.1 m wide, survives as the crypt in the south transept, reached by six steps, with its ceiling slabs forming the transept floor. The name Sept-Saints is common in the region, given to dolmens, menhirs and springs alike.

The chapel's name comes from the Seven Sleepers of Ephesus, a name common in the region for dolmens, menhirs and springs. A stream rises nearby from seven springs. The pardon is held on the fourth Sunday of July, when an imam recites from the Quran at the fountain beside a Christian mass, bringing Christian and Muslim pilgrims to the same site.

The chapel is in Le Vieux-Marché, a small village most easily reached by car since public transport in the area is limited. Crowds are largest in July during the annual pardon, so visiting on other days offers a quieter experience of the site.

Directly beneath the chapel floor sits a prehistoric dolmen whose stones were reused to build the structure above it. Inside the dolmen, rough 18th-century statues show the seven saints lying down, as though asleep, mirroring the legend of the Seven Sleepers.
