A UNESCO World Heritage Site, San Gimignano is one of the top sights to see in the province of Siena. Nicknamed the Medieval Manhattan, the town had 72 towers in the 13th century, of which only 14 remain standing today. The town’s nobility competed to build the highest tower and demonstrate their power. You will feel like you’ve gone back in time to the Middle Ages as soon as you enter the city gates! An essential stop on your tour of Tuscany.
