Piazza Grande, the most beautiful public square in Arezzo, is opened in the heart of the medieval city, the square is a mix of buildings of several ages that gives an evocative and scenographic aspect. It has a characteristic trapezial shape, with a strongly tilted surface, the square was the ancient Platea Communis, risen around 13th century and then modified in the course of 16th century, when the public square was reduced to the current dimensions with the realization of the Vasarian Loggia. The square, in the communal age, was a place of mercantile exchanges between the city and the country, and then, in Medicean age, became the center of the civil offices.
Between the buildings that characterize the square, are worthy of mention the imposing Palace of the Logge, constructed in 1573 from Georgio Vasari (1511-1574), the palace is opened by an immense and beautiful colonnade on which still are old craftsmen shops and business activity.
