The seat of 13 Nguyen-dynasty emperors between 1802 and 1945, Hue was once Vietnam's splendid Imperial City. Although it was devastated by the French in the 19th century and again by fighting between the Vietnamese Communists and the Americans in the 20th, the monument-speckled former capital has a war-ravaged beauty. One can still imagine its former splendor, despite gaping holes in its silhouette. Hue is a UNESCO World Heritage Site, and the city's gems are slowly being restored.
