Halles de Châtillon-sur-Chalaronne, Medieval market hall in Châtillon-sur-Chalaronne, France.

The Halles de Châtillon-sur-Chalaronne is a market hall in the town center featuring a wooden structure with three bays supported by massive oak pillars. The timber framework creates a sheltered space that covers the entire marketplace below.

The hall was built in 1440 and rebuilt in 1672 after a fire, with support from Mademoiselle de Montpensier, cousin of King Louis XIV. This reconstruction allowed the building to survive and remain functional for centuries.

The hall hosts a fresh-produce market every Saturday morning and doubles as a shelter when outdoor events are caught by bad weather. It also stages part of the programme of the Cuivres en Dombes brass festival. The building stands on the Place de la Halle, beside the half-timbered houses of the old town.

The hall stands on the Place de la Halle in the old town, beside the Saint-André church and the half-timbered houses. The Saturday morning fresh-produce market fills the building, and the open sides also shelter outdoor events caught by rain.

The hall is held up by 89 wooden posts, and its roof and floor were renewed between 1898 and 1900. Look up at the angled braces that rise from the posts to the roof beams, forming pointed arches beneath the projecting eaves.
