Very worth a visit along the Garonne River: a mighty gate with a fine city museum.
Important city gate and triumphal arch.
One of the city's most visually striking spots is this gateway in the old city wall, built as a triumphal arch in honour of Charles VIII for achieving an armistice in the Battle of Fornovo on the Italian peninsula in 1495; his statue crowns the structure. Built in impressive Gothic-Renaissance style on the banks of the Garonne River, it also served to monitor and control access to the city. The name "Cailhau" derives from the rocky river sediment used in its construction. Check its admission booth for opening days and hours of the interior, where you'll find an interesting museum of city history and get a very photogenic view over the Garonne.
