The largest Franciscan church in the world, the Basilica of Santa Croce contains frescos by Giotto and a chapel in the cloister designed by Filippo Brunelleschi that is considered one of the masterpieces of Renaissance architecture. In 1322 the Pope declared that the Franciscans' vow of poverty was illegal, that Christ had, in fact, owned property and wanted his followers to own property. This meant, of course, that the Franciscans were forced to collect money and land which would in turn go to the Pope.
