Basilique Saint-Mathurin de Larchant, Gothic basilica in Larchant, France.

Basilique Saint-Mathurin de Larchant is a Gothic stone church with a 50-meter tower and multiple carved portals showcasing detailed sculptural work. Inside, sturdy buttresses support the semicircular choir area and reinforce the overall structure of the building.

The basilica gained importance in the early 11th century when Elisabeth Le Riche donated Larchant to the Notre-Dame Cathedral of Paris chapter. This gift transformed the settlement and established it as a significant religious center in the region.

Pilgrims came to Saint Mathurin's tomb seeking cures for madness and possession; the pilgrimage peaked in the late Middle Ages, drawing kings from Charles IV in 1325 to Henri IV in 1599. It faded after the Revolution, and a ceremony honouring the saint is held again on Whit Monday.

Entry is through the side doors of the transept, not the ruined west front. The nave is partly in ruins and the south side of the bell tower has collapsed, so some areas are seen from outside. The interior is 57 m long and the vaults rise 18 m. A ceremony honouring Saint Mathurin is held on Whit Monday.

The north tower portal displays architectural features that closely resemble those found at Notre-Dame Cathedral in Paris, pointing to craftsmen who may have worked on both buildings. This connection reflects the close ties between the two religious sites during the medieval period.
