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/

The castle overlooks the Ain plain. A few benches are available for relaxing while admiring the view. It's possible to walk around the castle by continuing along the path past the entrance. It's accessible with a paid ticket, and opening hours vary depending on the season.
