There’s a small, red theater in Aix-en-Provence. It’s located in a narrow street south of and parallel to Cours Mirabeau. They call it “Il Piccolo”.
It’s not the smallest theater in the world though. That one is accidentally located in Villach, the town where I currently live. 1.3 times 1.3 meters, with a capacity for an audience of eight! How’s that for a record 🙂
