The world renowned leaning tower is not the only architectural marvel Pisa has to offer. This ancient city has a rich history with beautiful churches and bridges dating back to 12thcentury. We drove to Pisa from Rome while we were backpacking through Europe and visited Piazza deiMiracoli, the square of miracle which consists of four unique structures. These stunning structures form a complex that includes the famous leaning tower of Pisa and a cathedral. Did you know that the leaning tower of Pisa weighs approximately 14,500 tonnes? The top floor of the tower, the bell chamber, offers the best view of the city.
