The Order of St John granted the islands of Piskopi (Tilos) and Kalkia to Borello Assanti of Ischia at two hundred florins a year. It does not appear that he became a vassal of the Order but the terms of the contract made clear that he had to provide the guard service. The Order reserved the superior lordship of the island while the falcons of the island were reserved for the master as were the rights over shipwrecks. Assanti was also constrained from exacting any service from the islanders that had not been exacted by the Order in the past.
The tower at Stavrou Lambrou is built on an eerie high above the tallest sea cliffs on Piskopi. It is the strongest naturally fortified site on the island.
