The Knights’ Square or Piazza dei Cavalieri, lined with splendidly decorated buildings, has for centuries been the political heart of Pisa and is the second most important square after The Square of Miracles. A visit to the Renaissance church of Santo Stefano dei Cavalieri will give you a real insight in the colourful maritime history of the city.
It was in this square that in 1406, Florence’s emissary proclaimed the end of the independence of Pisa. One hundred and fifty years later Cosimo I de Medici, Grand Duke of Tuscany, asked his favourite architect Giorgio Vasari to modernise this space in Renaissance style. He dedicated the square to his recently founded military order of the Knights of Saint Stephen, whose duty it was to fight the advancing Ottoman Empire.
The Knights’ Square – What to see
Palazzo dei Cavalieri was also known as “della Carovana” (Palace of the Convoy). This name derives from the three-year training period undertaken by the initiates of the Order, called “la Carovana”. Vasari embellished it with exquisite sgrafitti, that represent allegorical figures and signs of the zodiac, and the busts of the Grandukes of Tuscany. In front of it stands the huge statue of a victorious Cosimo I proudly ‘squashing’ the head of a dolphin, as a symbol of his naval victories. Today the palace hosts the Normale di Pisa University.

The Church of the Knights of the Holy and Military Order of St. Stephen was also designed by Vasari (1565–1569). It contains Ottoman and Saracen naval banners captured by the Knights of St. Stephen. The ceiling shows off paintings with historical episodes involving the order, like the “Return of the Fleet” from the Battle of Lepanto.
The Palazzo dell’Orologio (Clock Palace) was the seat of the government in Medieval time. It was the setting of the dramatic story of Count Ugolino della Gherardesca, a traitor of the city who was left there to die of hunger with his sons and grandchildren. In one particularly gruesome scene in the Divine Comedy, Dante tells us that he ate them to survive. Today the Palazzo hosts the University library.
