Musée Carnavalet Le Marais, Ménilmontant & Belleville

Paris' history museum, spanning Gallo-Roman times onwards, rambles over a pair of remarkable hôtels particuliers (private mansions), the 1560-built Hôtel Carnavalet and 1688-built Hôtel Le Peletier de St-Fargeau. The museum is expected to reopen after a four-year renovation by summer 2020.
