Leave the archeological ruins and the history of Agrippa behind as we continue the hike alongside the sea. While walking, observe the large amount of posidonia on the banks, carrying out the important role of containing the sand. Resting on the rocks off the coast, we can see some cormorants, while the route continues to move inland, reaching the ruins of the Casa del Marchese, known as the Convalescenziario (convalescent home in English). True to its name, this was where sick prisoners, particularly those suffering from tuberculosis, spent time recovering, and, for preventive measures, it was decided to use the building furthest from the port. After a short while, we’ll come across another beautiful cove, boasting a thousand shades of colour. What today is a beautiful landscape, for the Ancient Romans must have been “a deceiver for explorers,” a landing point that was anything but peaceful and safe, as the amphorae discovered here tell us. The seabed is often low along the coast, making Pianosa difficult to dock at. Back in the town, after a restorative break, visit the exhibition that recounts the history of Pianosa, its settlement and the penal colony. Before returning to the port, take a walk through the ghost town, with streets named after people tied to the fight against the mafia.
