This museum of military hardware and the city's fortifications received a major facelift in 2015. The collections are housed in three buildings along the city's western bastions. One building is given over to weapons from the 15th to the 19th centuries, while a separate structure houses weapons from the 20th century. A third building shows an entertaining film of the city's history (ask for English-language headphones). Screenings are on or near the hour throughout the day.
