The church Saint-Pierre et Saint-Paul is a part of the charm of the village.
Tthe frontage dates from 12nd and 17th centuries, the choir and the transept from 12nd century. The nave is belated. The date of 1661 wrote on a keystone suggests a restoration at the 17th century. The frontage is opened by a central gate Renaissance with two doric pillars. The bell-tower is end of 16th century.
The old church undoubtedly destroyed by a fire in 16th century did not include a chorus, a transept and a nave. At the 17th century, the nave was increased, the collateral additions just as the bell-tower. Left from the choir, was the vault of the Lords containing the tomb stones of the first lord de Montigny, Jean de Boissière (deceased in 1575), Grand Louvetier of King François 1st and his wife Hilaire Raguier (deceased in 1593).
In 1793, the bell called"Louise" the name of the lady de Montigny in 1619, Louise de Vignacourt, was transferred to Genevraye. The altar was built in 1845.
Dedicated to the Holy Virgin then to Saint-Vincent, this alta is made of sandy concretions looking like grapes coming from La Roche-à-Boule located at the edge of the Fontainebleau forest on the top of the village.
