At the heart of the historic centre is the vast expanse offered by the Place d’Arçon where the town hall and the Pontarlier museum are both located. The first was completed in 1838 and originally housed an indoor market on the ground floor. The museum is located in one of the city’s oldest buildings, a combination of three houses, the oldest of which dates back to the 15th century. (PNRHJ - Un tour en ville, “A tour of the town”)
