Visit Pian dei Giullari, with Villa il Gioiello, where Galileo spent his declining years, and with the Observatory of Arcetri nearby. The road then continues in the direction of Mount Oliveto, famous for Villa Strozzi, Villa di Bellosguardo and especially Villa Calamai because Ugo Foscolo stayed there as the guest of Quirina Mocenni when he was writing "Le Grazie" (1813).
