Centrale nucléaire de Saint-Alban
Nuclear power plant in France.
Each edition grades its towns against each other only.

Most of what there is to see is châteaux or heritage sites: 7 of 11. Chavanay itself has none of them. A longer outing takes you to Musée des Beaux-Arts de Lyon, 40 km off.
The list goes on from Centrale nucléaire de Saint-Alban to 3 châteaux, a museum and a water park.

From OpenStreetMap and Wikidata: named museums, galleries, châteaux, abbeys, gardens, zoos, theme parks and other visitor attractions whose mapped point lies inside the commune of Chavanay, then those in the communes within 5 km of its centre, and well-known places within 40 km. Houses, ruins and gardens need a sign they’re open to visitors; places marked private, closed or disused are left out. The historic-monument link is the Culture ministry’s Mérimée record. A place that isn’t mapped isn’t listed, so this isn’t everything there is to see.
