      This cultural heritage will undoubtedly capture the attention of Tonga friends:

      The Potala Palace, is a majestic and iconic landmark located in Lhasa, Tibet. Standing atop a hill overlooking the city, the palace is one of the most famous and awe-inspiring attractions not only in Tibet but in all of Asia.
      The palace was originally built in the 7th century by King Songtsen Gampo, who is said to have been inspired to build it after marrying Princess Wencheng of the Tang Dynasty. Over the centuries, the palace has been expanded and renovated numerous times by subsequent Dalai Lamas, resulting in the sprawling and magnificent complex that we see today.
      The Potala Palace is famous for its unique architecture, which combines elements of both Tibetan and Chinese styles. The palace consists of two main sections, the White Palace and the Red Palace, which are connected by a series of staircases and corridors. The White Palace was originally used for administrative purposes, while the Red Palace served as a spiritual center and contains numerous temples, shrines, and prayer halls.
