Basilica of St. Francis
The basilica is definitely worth seeing, and is one of the biggest attractions in Assisi. The inside is absolutely beautiful with all its paintings, but unfortunately flash photography is not allowed. I recommend you don't visit during a religious holiday or pilgrimage, because it can get very crowded during those times.
The tomb of Saint Francis is in the basement of the basilica, and there are also relics (such as his robe).
Assisi is the birthplace of St. Francis (San Francesco) and his life and ideology have transformed this medieval town into a monumental shrine, which draws thousands of pilgrims and visitors. Shops selling all sorts of religious objects are everywhere.
Assisi: the San Francesco's town
"Assisi; an open museum."
Diocese located in the civil province of Umbria, Italy. The town of Assisi, which takes its name from Mount Asi, on which it is situated, lies amost in the centre of the province of Umbria, about halfway between the cities of Perugia and Foligno.
Everywhere you look in Assisi, you'll find another fine church, mostly built in the pretty pink stone which defines the town's appearance, and mostly containing fine artworks and a few Franciscan relics. The grandest of these, of course, is the Basilica di San Francesco.
In the San Francesco church there are plenty of frescoes attributed to Giotto, Cimabue, Simone Martini and others that can be admired free in the church.
Assisi's other attractive churches are numerous; among the finest are the Basilica di Santa Chiara.
