The Lake has three islands: Isola Maggiore, Isola Minore and Isola Polvese. The largest is the Polvese Island which extends for 69.6 hectares; it is open to visitors even if it has belonged to the Trasimeno Regional Park since 1995 and, besides the beautiful views, offers visitors three points of interest: the Rocca, the ruins of the Olivetan Church of San Secondo and the Church of San Giuliano. The only inhabited island is Isola Maggiore, which has various structures and monuments to see: the docking area (via Guglielmi) with its palaces, the Church of San Salvatore, the ruins of the monastery church of the Sisters of San Leonardo, the ruins of the Roman Tower and much more. Moreover, not everyone knows that the Isola Maggiore was one of the places dear to Saint Francis of Assisi who stayed there and meditated during the Lent of 1211. The third island, the Isola Minore (also called Isoletta) is private and not open to visitors. It is currently uninhabited, although it has been inhabited by many families until the fifteenth century.
