You'd think a medieval tower in central Paris would be rather conspicuous, yet this early 15th century structure timidly blends in among its more recent neighbouring buildings.
Once inside, you can visit a temporary exhibition on the dukes of Burgundy in the basement - Jean sans Peur being one of many - or climb the stairs to read numerous signs about daily life in the Middle Ages. As a museum, it felt a bit old-fashioned (Reading signs requires attentive visitors. As a teacher, I know not all visitors always are. Attentive, that is.) though as a quirky Paris oddity, it's just fine.
