Arezzo Tours, Travel & ActivitiesThe Piazza Grande is the most noteworthy medieval square in Arezzo, opening behind the 13th century Romanesque apse of Santa Maria della Pieve. Once the main marketplace of the city, it is currently the site of the Giostra del Saracino ("Joust of the Saracen"). In this, "knights" on horseback representing different areas of the town charge at a wooden target attached to a carving of a Saracen king and score points according to accuracy. Virtually all the town's people dress up in medieval costume and enthusiastically cheer on the competitors.
