Its legacy as the former imperial capital of Vietnam is just one of many reasons to visit Hue. For more than a century, the emperors of the Nguyen dynasty (1802-1945) ruled from the Forbidden Purple City, the innermost enclosure of the citadel. Today, this complex is designated as a UNESCO World Heritage site and draws millions of visitors each year. Besides stimulating the tourism industry, Hue's rich history has also had a significant impact on the culture and characteristics of the city and its people, including naming customs, fashion, and cuisine.
