Located about 20km west of Hue Imperial City, Emperor Gia Long's Mausoleum (or Thien Tho Mausoleum) is a relic of the Complex of Hue Monuments, which has been recognized by the UNESCO as a World Cultural Heritage Site.

On the first day of the Lunar New Year of the Snake, heritage sites in Hue opened their doors for free, welcoming thousands of visitors to experience the festive atmosphere of the traditional Tet holiday.

In addition to the Hue heritage system, a large number of domestic and international tourists came to visit and offer incense of paying tribute at other historical sites in the province, with the largest number of tourists were at the Chin Ham historical relic site (An Tay Ward) and the Phan Boi Chau memorial site (Truong An Ward, Hue City).

Inside the Hue Royal Palace heritage site, at Duyet Thi Duong Theater (the theater for the king, royal family members, and mandarins to enjoy traditional royal operas) stands a space exhibiting hundreds of tuồng (traditional Vietnamese opera) masks, which get tourists to stop to explore.

According to the center's assessment, the increase in the number of visitors to the heritage sites was thanks to the effects of the Four Seasons Festival and corresponding festivals.

With the efforts of local authorities, the Government as well as international organizations, after 30 years of being honored as a world heritage site by UNESCO, the Complex of Hue Monuments has gradually recovered its original appearance and is in its phase of stability, development and value promotion.

Promotional videos focus on introducing Thua Thien Hue tourism with diverse perspectives, especially the massive heritage system, the destination of 5 world heritage sites, along with the images of green, peaceful destinations, festivals, and special cuisine.
