Arezzo

Rising during the pre-Etruscan era, Arezzo became a very important junction for the Roman Empire, thanks to its strategic position for crossing the Apennines. In the Middle Ages, Guido Monaco, a Benedictine monk of Arezzo origins, created the tetragrammaton, the predecessor of the more modern pentagram. Piazza Grande is not only the geographical centre of Arezzo, but also the site of the Joust of the Saracen, probably the most important event in the city, which pits the four quarters of the city against each other in a simulated military training in medieval style.
