Ensconced in the banks of a peaceful river at the heart of Dombes, the charming medieval town of Châtillon-sur-Chalaronne, a floral town with a 4-flower rating and winner of the National Floral Grand Prix, contains wonderful heritage buildings within a magnificent floral setting. These include the picturesque timber-framed houses, old 17th-century wooden market hall, the gate of Villars, the Church of Saint-André in the flamboyant gothic style, Saint Vincent de Paul House, and the relics of the old castle. The floral bridges and riverbanks of the Chalaronne are ideal for a leisurely stroll and make an enchanting sight for walkers and flower-lovers.
Also worth seeing are the Traditions and Life municipal museum, all about rural life in Dombes and Bresse in the early 20th century, and the former hospital with its apothecary dating from 1814, adorned with a collection of 120 ceramic pots from Meillonnas.
A traditional market full of local produce takes place every Saturday morning in the covered market at Châtillon-sur-Chalaronne.
