Huế is a city in central Vietnam that was the seat of Nguyen Dynasty emperors and the national capital from 1802–1945. A major attraction is its vast, 19th-century Citadel, surrounded by a moat and thick stone walls. It encompasses the Imperial City, with palaces and shrines; the Forbidden Purple City, once the emperor's home; and a number of the Royal tombs.
Hue owes its charm partly to its location on the Perfume River – picturesque on a clear day, atmospheric even in less flattering weather. Today the city blends new and old as sleek modern hotels tower over crumbling century-old Citadel walls.
