Origin and history
The church of Saint-André de Boissy-l A first Christian sanctuary was built between the 4th and 5th centuries under the impulse of Nicaise de Rouen, as evidenced by the baptismal fonts today preserved at the Tavet-Delacour Museum in Pontoise. Archbishop Jean d'Ivry offered the church to the abbey of Saint-Denis in 1071, marking his lasting connection to the archdiocese of Rouen and to the French Vexin.
In the twelfth century, a Romanesque nave was built, followed by a Gothic choir in the thirteenth century. The building suffered major damage in 1433 during a fire caused by the Anglo-Normands after their expulsion from Pontoise. Rebuilt in the same way, the church was again consecrated in 1463. In 1691, the snack of the cure passed to the royal house of Saint-Louis, linked to the local seigneury. A tragic turn occurred in 1781 when lightning struck the bell tower, already weakened: its collapse in 1796 destroyed the nave, leaving the church in ruins for half a century.
The partial reconstruction of the choir between 1848 and 1850 saved the building of total disappearance. Only the northern half, including the north transept cruise and part of the elevations, was preserved; The rest was reconstructed identically, although stylistic compromises (such as unsculpted capitals) betrayed this intervention. The bell tower was never rebuilt, and the abandoned nave left room for a court. In 1926, the choir was inscribed in historical monuments, excluding the transept despite its partial authenticity.
The architecture of the church reflects these historical strata: the Gothic choir, marked by an elevation on three levels (bottoms, triforium, high windows), is inspired by the cathedrals of Laon and Soissons. On the outside, the western facade, rebuilt in 1848, imitates the 13th century style without excessive ornaments, while the bedside retains authentic elements, such as a triplet of lancets and a rosette with wooden reamping. The interior reveals remarkable details, such as sculpted capitals of d'acanthe leaves or nenuphars, and a triforium with various arcades.
The classified furniture includes a 16th century tumular slab, representing an ecclesiastical and his parents, as well as a statue of the Virgin with the Child and the Baptist fonts of the 15th century, all protected as historical monuments. These elements illustrate the religious and social importance of the church, from its medieval parish role to its modern preservation, despite the vicissitudes of history.
