The church of Saint-Laurent de Beaumont-sur-Oise is a parish church of the 12th and 13th centuries, with a basilical plan with five vessels, modelled on the cathedral of Bourges, but with a flat bedside. The work began under the Counts of Beaumont and remained unfinished in the thirteenth century, which explains why the nave’s ribbed vault dates only from the nineteenth century. The church has Gothic capitals of exceptional quality that bring it closer to Notre-Dame de Paris. The bell tower, built during the sixteenth century, is a high tower crowned by a dome with abundant Renaissance sculpture with a whole vocabulary reminiscent of the castles of Écouen or Fontainebleau. It can be compared to the bell towers of Pontoise, Pont-Sainte-Maxence and Senlis.
