It's no coincidence that the word "muse" is in "museum!" International Shoe Museum aims to inspire and entertain its visitors, so add it to your to-do list.
You'll have sightseeing choices galore when staying in Romans-sur-Isere. International Shoe Museum is a great place to kick off here, but there are lots of other worthy attractions to check out. Jardin Zen d'Erik Borja, Excalibourg, and Centre Historique de la Résistance et de la Déportation are close to the museum and will fill in your day nicely.
