Angkor Wat, also known as Angkor Wat, is also the largest and best preserved building in Angkor's monuments. Therefore, "Angkor Wat" is also known as the general name of the entire monument. Angkor Temple consists of four corridors in the southeast and northwest (each wing is divided into two wings), the West Gate Road, the main entrance, the triple cloister and five spires centered on the central minaret of the main hall. The spires on the top of the tower are said to represent "heaven". The steps are steep and slippery. They can only climb up and down with their hands and feet, allowing believers to experience the hardships of the road to heaven during the climbing process. In the previous step, there was no handrail. In 1973, a French female tourist fell to death and her husband mourned to donate money on the side of the steps to avoid the recurrence of the tragedy. From this side of the ladder is also known as the "love ladder." The perfection of Angkor Wat in architecture and sculpture makes it a symbol of Angkor's monuments and even the whole country, and appears on the national flag of the Kingdom of Cambodia. The ancient working people of Cambodia used the basic principles of architecture in the construction of Angkor Wat, using the principles of perspective and symmetry to make people see the whole picture at a glance. In addition, the Angkor Temple is built with stones weighing 8 tons each. Without the use of mortar or other adhesives, the craftsmen simply stack them by the weight and shape of the stones. It can be learned from the Cha Cha Temple that the Angkor Wat was first piled up and carved.
