Hue Imperial City

The Nguyen dynasty capital from 1802 to 1945 contains a UNESCO-listed citadel complex of 140 monuments including the Imperial Enclosure, the Forbidden Purple City, and seven royal tombs spread along the Perfume River -- the most concentrated collection of imperial Vietnamese architecture in existence. Hue royal cuisine, developed for emperors who demanded 50 dishes per meal, has been recognized by UNESCO as Vietnam's most sophisticated culinary tradition, and the city's banh mi and bun bo Hue are considered the finest versions of those dishes in Vietnam.
