Hue

The former imperial capital of the country from 1802 to 1945, Hue is often referred to as Vietnam’s most beautiful city and has long been a major cultural, religious and educational centre. 

Surrounded by moats, the intriguing Purple Forbidden City which served as the residence of the Nguyen Emperors was constructed by Emperor Gia Long in 1804. Largely destroyed during the American War, the remains of the citadel, which have been partially restored, still contain interesting sights.
