A spiderweb of narrow lanes, Terra Vecchia is Bastia’s heart and soul. Shady place de l’Hôtel de Ville hosts a lively morning market on Saturday and Sunday. One block west, baroque Chapelle de l’Immaculée Conception , with its elaborately painted barrel-vaulted ceiling, briefly served as the seat of the short-lived Anglo-Corsican parliament in 1795. Further north is Chapelle St-Roch , with an 18th-century organ and trompe l’œil roof.
