Florence, Italy — View from the cupola atop Florence’s Duomo toward the southeast. The church at left is the Basilica of Santa Croce. The tower near the lower right edge is the Bargello. Running along the foot of the hills in the distance is the River Arno. Just across the river, to the right of Santa Croce, is the Porta San Niccolò, one of the city’s medieval gates built in the 1320s.
