None of our places to visit is in Mons; 3 are within 5 km of its centre. They include an abbey, a museum and a château. A longer outing takes you to Cathédrale Saint-Pierre d'Angoulême, 27 km off.
Then come a museum and a château, behind Prieuré Notre-Dame de Lanville.
Best known first: by how many Wikipedia and sister-site articles cover each place (Wikidata’s count). It isn’t a ranking of how good they are.

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 Mons, 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.
