The Basilica of San Francesco, with its cycle of frescoes on the life of the saint made by the hand of Giotto, has marked the art and spirituality of Italy and the world. Its construction began two years after the saint's death, and in just two years the Lower Basilica was completed, while the upper one was consecrated in 1253. The decorations are the result of the most illustrious painters between the thirteenth and fourteenth centuries such as the Master of St. Francis, Cimabue and Giotto, who created the "Stories of St. Francis" in the Lower Basilica of Santa Chiara, recognizable by its façade with bands of white and pink stone from Subasio.
