The Château de Théméricourt, probably built by Philippe de Théméricourt in the second half of the 15th century, has retained its initial plan with two main buildings arranged at right angles and flanked by four turrets topped with pepperbox roofs. This square plan responds to the concern of rejecting common areas in isolated buildings. The north and west facades of the castle have retained their original, very severe appearance. They contrast greatly with those opening onto the park, which, apart from the central turret, remain marked by classicism. The castle park has evolved greatly since the 18th century. The French garden was succeeded, it seems in the middle of the 19th century, by a park with a pond fed by the Aubette de Meulan.
