Église Saint-Pierre

The Church of Our Lady of Boissy-en-Drouais was built in the twelfth century by William of Champagne, bishop of Chartres, and almost completely rebuilt in the fifteenth and sixteenth centuries in a Gothic style. At the time of the Revolution the church was stripped of furniture and rich ornaments. The church has a high bell tower and a nave, vaulted with painted shingles. Its large door is remarkably adorned with entablatures, columns and jambs surmounted by a shell, made of Paris stone.

The Church of Saint-Christophe is located in Mondreville, in Île-de-France. It displays the harmonious coexistence of Romanesque elements in the nave and the Gothic style in the choir and carved 16th century decorations on the nave frame. The building, topped with a small bell tower with an octagonal spire, is endowed with a rich movable heritage such as a statue of the Virgin and Child, from the 15th century.

The chapel of Notre-Dame de la Brèche (Our lady of the breach) was built in 1599, after the Protestants in 1568, during the second war of religion: a breach having been opened in the city walls by the artillery of Louis de Bourbon-Condé, the Chartrains, under the protection of a statue of Notre-Dame de la Porte Drouaise, built and defended a barricade which prevented the capture of the city. The chapel was rebuilt in 1843 to serve the parish of the lower town, the neighbouring Saint-André church having been disused during the Revolution.
