Cambodia Angkor Wat (Angkor Wat), also known as Angkor Temple, is located in Cambodia and is known as Cambodia’s national treasure. It is the largest temple in the world and the earliest Gothic building in the world. The original name of Angkor Wat is Vrah Vishnulok, which means "Vishnu's Temple". Ancient Chinese Buddhist books call it "Sangxiang Buddha House". In the 12th century, King Suryavarman II of the Angkor Dynasty wanted to build a magnificent cave temple on the ground as the capital and national temple of the Angkor Dynasty. Therefore, it took a nationwide effort and took about 35 years to build. It is the best-preserved building among the Angkor monuments and is world-famous for its architectural grandeur and detailed reliefs. In 1992, UNESCO listed the Angkor monuments as a World Cultural Heritage. Since then, Angkor Wat has become the most important tourist attraction in Angkor and has become a bright tourist card in Cambodia. For more than a hundred years, countries around the world, including China, have invested a lot of money and manpower in the maintenance of Angkor Wat to protect this world cultural heritage. The shape of Angkor Wat has become a national symbol of Cambodia and is displayed on the Cambodian flag.
