Joust of the Saracens
Arezzo is home to an annual medieval festival called the Joust of the Saracens Giostra del Saracino. 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.
Arezzo is also home to an annual popular music and culture festival, each July 17-22 July 2007, called ArezzoWave. Publicly funded, it attracts bands of high repute and attendees from all over Europe and North America. It also features literary and film expositions. From summer 2007 Arezzo Wave will move to Florence.
The Arezzo Festival (http://www.arezzofestival.it/) - an annual summer theatre festival that brings together emerging professional and university-based performance groups from all over the world.
