This image is of the Rose Window of the Papal Basilica of St. Francis of Assisi in Italy, known as the mother church of the Roman Catholic Order of Friars Minor, commonly known as the Franciscan Order.
Burial place of St. Francis, 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 two churches known as the Upper Church and the Lower Church, and a crypt where the remains of the saint are interred.
The doors of the Lower Basilica Church are surmounted by this large rose window, flanked by two smaller ones, called “the eye of the most beautiful church in the world”. (from Wikipedia.org)
