The Papal Basilica of St. Francis of Assisi is the mother church of the Roman Catholic Order of Friars Minor in Assisi, where St. Francis was born and died. The basilica is one of the most important places of Christian pilgrimage in Italy. The basilica, which was begun in 1228, is built into the side of a hill and comprises 2 churches known as the Upper Church and the Lower Church, and a crypt where the remains of the saint are interred. The interior of the Upper Church is an important early example of the Gothic style in Italy. The Upper and Lower Churches are decorated with frescoes by numerous late medieval painters from the Roman and Tuscan schools, and include works by Cimabue e Giotto.
