The Column of Justice
The Colonna della Giustizia (Column of Justice), which stands in Piazza Santa Trinita, was presented to Duke Cosimo I de' Medici ( r. 1537-74) by Pope Pius IV (r. 1559-65).
The 11-metre-high granite column, which came from the ancient Roman Baths of Caracalla, arrived in Florence in 1563 and was placed on its pedestal in 1565.
The column marks the victory of Florence against Siena at the Battle of Marciano (August 2nd, 1554). It was erected on the spot where the duke first heard news of the triumph.
In 1580, the statue of Justice was added to the top of the column. The statue, which is made from three blocks of porphyry, one of the hardest stones to work, took the sculptor Francesco del Tadda (and his son Romolo) almost 11 years to complete.
