From Monte Le Penne, continue along a path that winds once more through the fragrant Mediterranean scrub and which runs along the base of Monte Castello, the highest on the island. Head down through the areas that once belonged to the penal colony, which closed in 1986 after nearly 100 years of activity. Walk through the prison’s abandoned buildings as you try to imagine what day-to-day life was like in this small fortified colony. You’ll come across the Aghiale, with the cells, housing for the guards, dining hall, barber and sheep pen, where the inmates carried out the colony’s typical farming activities, as well as the ruins of the former laundry. It should be said that the buildings belonging to the ex-penal colony are in a state of near or total abandon, and some of them, having been built at the end of the 1800s, were already not in the best condition when the colony closed down. Visitors are advised to take caution when exploring the ruins and to respect no entry signs.
Leave behind the former penal colony, passing through the arch that marks the entrance. From here, the fragrances of heather and Mediterranean scrub accompany you on your return to the port and the town.
