The Daming Palace National Heritage Park was built on the site of the Daming Palace in the Tang Dynasty. Seventeen emperors had run their state affairs from the Daming Palace of the Tang Dynasty. This had lasted for more than 200 years. Empress Wu Zetian and her husband, Emperor Gaozong of Tang, as well as Empress Wu’s daughter, the Princess Taiping, had all lived in the palace. Daming Palace was the most splendid palace complex in the world at the time and the center and symbol of the Tang Empire. Today, the remaining park is divided into two parts: a free area and a paid area. The toll zone comprises the core area of the scenic spots, including the remains of the Hanyuan Hall and Xuanzheng Hall as well as the Daming Palace Relics Museum.
