Château du marché

Château du Marché in Châlons-en-Champagne is a unique fortified bridge spanning the Nau river, originally part of the city's medieval ramparts. Rebuilt in 1602 by order of the vidame Philippe de Thomassin, it features a façade of chalk and brick characteristic of Champagne architecture. The structure incorporates historical nicknames reflecting its past uses—known as the Pont des Archers after the mounted police who kept horses there, and as Caisse d'Épargne because a bank occupied part of its plaza-facing side. A 300-meter tunnel passes beneath the city through the arches, creating a distinctive waterway passage. This architectural relic stands adjacent to the Petit Jard garden, serving as a testament to medieval urban design.
