Siena is a very beautiful old mountain city built on a mountain. It was listed as a World Cultural Heritage Site by the United Nations in 1995. Its red brick buildings are located in a vast green forest and look like something from a fairy tale. You can stroll along the winding stone road to Piazza del Campo. The horse racing festival is held in the square in July and August every year. It is a major event in the area. The architecture blends medieval and Renaissance styles. The well-preserved old buildings are a testament to the town’s long history.
