The roof and shore of the museum, it is decorated with the shape of "bipedal paintings" and the shape of "four spirits: dragon, qilin, turtle, phoenix". Many fine art researchers have agreed that this is “a magnificent building in the most beautiful of Vietnamese palaces”.
Today, visitors to Hue Royal Antiquities Museum can admire hundreds of rare and precious artifacts such as thrones, palanquins, long sieves, royal robes, queen comedies, paintings, crockery, silverware, bronze, painted enamels... with hundreds of years old. These are handicraft products made by the “golden hands” once made by the court or to provide for the king. They are not mass-produced items, but each has only one set or a single one. Rare and unique, that is.
The museum is also home to thousands of other artifacts produced by the Nguyen court, ordered, or purchased from abroad, and donated by diplomatic missions. The most common is the blue enamel porcelain, often referred to as "Bleu de Hue".
In the premises of Hue Royal Antiquities Museum, there is also another warehouse storing more than 80 Cham artifacts collected in the area of ancient Europe and brought from Tra Kieu during archaeological excavations there in 1927. Cham artifacts have been evaluated by researchers as rare cultural heritages not only of the Far East but also of the world.
