The Fortifications of Xi'an, also known as the Xi'an City Wall, are some of the oldest and best-preserved city walls in China. Built under the rule of the Hongwu Emperor Zhu Yuanzhang in the 14th century, this massive wall encloses an area of about 14 square kilometers. With its impressive ramparts, watch towers, and gates, the wall showcases the architectural prowess of feudal society. Over the years, it has undergone several renovations and is now a popular tourist attraction in Xi'an, offering visitors a chance to walk along its historic walkway and soak in the ancient charm of the city.
