St. Denis Church, Méry-sur-Oise

The Saint-Denis church is a Catholic parish church located in Méry-sur-Oise, France. It was almost entirely built between the end of the 15th century and the beginning of the 16th century, in the flamboyant gothic style, keeping the 13th century chevet. Its plan is very simple: a nave of six bays with a single side aisle of the same length, and a small side chapel. In the detail, some particularities appear nevertheless, such as the irregular configuration of the most western bays. Although the collateral represents the first part built at the end of the 15th century, as shown by the flamboyant portal and the year 1485 engraved in a keystone, its windows are in the Renaissance style, as are the capitals of the large arcades connecting the collateral with the nave. It must be a remodeling of the second half of the 16th century, but the history of the church has not yet been written. The close link with the castle of Méry and its lords is not in doubt, and a doorway connects the side chapel directly with the castle. However, the overall sober architecture of the church does not show any particular ambition, nor a need for representation. It is classified as a historical monument by order of April 2, 1915.
