Designed in the late 13th century by Arnolfo di Cambio (architect of the Palazzo Vecchio and the Duomo) but with a neo-Gothic facade added in 1863, the Franciscan church of Santa Croce (east of the Uffizi) has an important series of Giotto frescoes.
Arnolfo di Cambio designed Santa Croce before he went to work on the Palazzo Vecchio and the Duomo.
