North and South Facade
The three facades of St. Mark’s Basilica — North, South, and West — open out around the lower body of the basilica. The north facade, overlooking Piazzetta dei Leoncini, includes the famous Porta dei Fiori or the Door of Flowers, a 13th-century relief of Nativity.
The south facade, which overlooks the Grand Canal, has two elaborately decorated pillars in front of it called the Pilastri Acritani. On the corner of this facade are the porphyry group of the Tetrarchs and the truncated porphyry column, Pietra del Bando.
