Hue is well known for its historic monuments, which have earned it a place in UNESCO’s World Heritage Sites. The seat of the Nguyen emperors was the Imperial City, which occupies a large, walled area on the north side of the Perfume River

The city’s economy is primarily built around tourism, as it contains one of the few UNESCO designated sites in Vietnam, the Complex of Hué Monuments being a tourist attraction, alongside its moat and thick stone walls. The complex encompasses the Imperial City, with palaces and shrines; the Forbidden Purple City, once the emperor’s home; and a replica of the Royal Theater.[1] Nearly 4.2 million visitors had visited the city in 2019 and much of its historic landmarks are undergoing restoration.
