The ticket is 200,000 Vietnamese dong. I bought it in advance through Ctrip. It is only 62 yuan, which is a must-visit place in Hue. It is not very good. It depends on personal preference. The Hue Imperial City in Vietnam was built in 1802. In the fourth year of Gia Long in the Nguyen Dynasty (1805), it began to be expanded and renovated on a large scale. After decades of construction, it has reached its current size. Located in the center of Hue City, the Xiang River winds through the capital, the imperial city, the Forbidden City and the inner city. The overall building is roughly facing north and south. The architectural style is basically modeled after the Forbidden City in Beijing, while the outer city surrounding the imperial city building, the capital, is a French-style building. The city is square with a circumference of 9,950 meters. The imperial city is also square, surrounded by a moat, and each side of the city wall is more than 500 meters long. The Hue Imperial City is the largest existing ancient building complex in Vietnam, representing the highest achievement of ancient Vietnamese architectural art. It was listed in the World Heritage List in 1993.
