This Florentine piazza was designed by architect Giuseppe Poggi and built in 1869 on a hill just south of the historic center, during the redevelopment of Oltrarno, the left (South) bank of the Arno river. In 1869, Florence was the capital of Italy and the whole city was involved in an urban renewal, the so-called "Risanamento" or the "Renovation" of the city's neighborhoods. Lungarni (riverside walkways; "lungarno", singular) were built on the riversides. On the right bank, the fourteenth-century city walls were removed and turned into the Viali di Circonvallazione, mimicking the French "boulevard" design, six lanes wide and lined with trees. On the left bank winding up the hill of San Miniato the Viale dei Colli was built, a tree-lined street over 8 kilometers long ending at the Piazzale Michelangelo which was built as a terrace with a panoramic view of the city.
