The city of Hue, Vietnam is home to a myriad of amazing sites associated with the ancient capital that was founded on the northern bank of the Perfume River in the 17th century. Located about 660 kilometers from Hanoi, the city is practically an open-air museum filled with hundreds of temples, palaces and tombs. A few must-see sites include the Forbidden City, which is a replica of the real Forbidden City in Beijing, China, and The Citadel, which is an early 19th century fortress complete with a wide zigzag moat and a defensive wall 21 meters thick.
