Purely unplanned, I arrived in Toulouse in the middle of a city-wide Photography Festival. Among many exhibitions that I visited during my short stay, the one inside the Eglise des Jacobins was by far the most impressive. [Exposition du collectif "8 reg'Art" - www.8regart.com]
However, this gigantic structure is; to me, the most beautiful monument Toulouse has to offer, even without that breathtaking photo exhibition inside.
