Collonges This is the most important spring in the village. The washhouse was built on the foundations of the "Tour de la Fontaine", then enhanced in 1830 with an almost square building with a classical-style colonnade. It was classified as a Historic Monument in 1973. Like a sanctuary, it serves as a setting for the precious spring, symbolically represented by a statue of the Virgin Mary placed in a niche. The four-sided roof with a steep slope is covered with scale tiles topped with a weather vane. It was used to turn a walnut oil mill. https://saint-sorlin-en-bugey.info/decouvrir-le-village/sources-et-lavoirs/

The Abbey of Ambronay was founded in 800 by Barnard de Romans, a soldier, an officer of Charlemagne, and a future saint canonized in 944. The abbey church, built on the ruins of the Carolingian church, features gargoyles, sculptures, and paintings that will amuse children with their fascinating details. The cloister is a space of serenity that invites meditation: your imagination may perhaps chase some ghostly figures of monks. The visit will end in the gardens where you will discover medicinal plants on the botanical trail. https://www.ain-tourisme.com/visiter-patrimoine/monuments-religieux-a-visiter-dans-l-ain/abbaye-benedictine-dambronay/
