The Basilica of St. Francis of Assisi is a UNESCO World Heritage site and a popular Christian pilgrimage site. Take some time to admire the frescoes by Giotto and Cimabue. The 1997 earthquake destroyed many of the Giotto murals but restoration was recently completed. Wander the neighborhood nearby to see small shrines on street corners and in alleyways. A nice hilly town for wandering. Parking lots conveniently located on outskirts of town - short walk.
