Corso Garibaldi begins in front of the Etruscan Arch and leads uphill to the Cassero (the fort above the Sant’Angelo Gate—see #3). Along the walk up the street, one can admire ancient houses alternating with ancient monasteries and small churches. An important fresco by Perugino depicting the “Madonna delle Grazie” between Saints Antonio Abate and Antonio Da Padova (1522) is kept in the Poor Clares monastery, Sant’Agnese. If you knock on the door, you may be let in to see it. On the path leading up to the convent there are numerous arches, gardens, smaller gardens and internal courtyards. Many of the houses along Corso Garibaldi are decorated with sacred pottery or stone designs, which once indicated the social status of the house owners and their membership in a trade guild.
