Château de Vincennes

Originally a hunting lodge, Château de Vincennes was the home of the French royal family for centuries, before they moved to the Palace of Versailles (and well before they were beheaded and banished). This historical compound has a moat, six towers, three gates, and a 52-meter tall keep - the tallest in Europe. This ticket includes access to all the key sights, and entitles you to enter via the priority entrance.
