The archaeological operation carried out at “Rue de Meaux” revealed certain elements of the defenses of the Meaux city-gate, and of a bridge, dated from the end of the 13th century, to the 16th century. In spite of the reduced surface and of the narrowness of the space available, limited as it was by the urban networks, the excavations brought to light a number of architectural elements of great interest. The fortified gate has a double entrance and a drawbridge with gaffs. It forms part of the defensive enclosure, preserved in the shape of a thick wall. The parts of the bridge which could be studied are: the first span from the gate, which supported a removable deck made of wood, and at least two arches of the fixed bridge. The two dressed stone arches of the fixed bridge rest on piers decorated with corbels. It was during the 2nd half of the 16th century that the course of the river Nonette was diverted to make room for a more impressive bastion. The excavations brought to light the final state of the bridge, at the time it was abandoned. A number of dressed stones from the bridge, the pier and the arches were salvaged, and the ditch was backfilled. The gate was levelled off, as well as the city wall on the East side of the gate. There were latrines situated close to the first pier of the former fixed bridge. Based on the samples taken in the ditch and the latrines, a study of the fauna was realized.
