Angkor Wat is a Hindu temple complex built to replicate the heavens on earth, and it literally means "City Temple". It was originally constructed for King Suryavarman II in the early twelfth century. It is the best-preserved temple and is the only one to have remained a significant religious center since its foundations; first Hindu, dedicated to Vishnu, later Buddhist. The temple is the summarize of the high classical style of Khmer Architecture. This magnificent temple integrates two basic plans of Khmer Temple architecture include the temple mountain and the later galleried temple, relied on early South Indian Hindu architecture. Constructed within a moat and an outer wall 3.6 kilometers (2.2 miles) long with three rectangular galleries, each raised above the next, it is designed to symbolize Mount Meru, home of the devas in Hindu mythology. At the center of the temple stands a quincunx of towers. Unlike most Angkorian temples, Angkor Wat is oriented to the west and this has scholars divided as to its significance. Furthermore, the temple is admired for the grandeur and harmony of the architecture.
Another Historical event of Angkor Wat, this temple has been listed and declared a World Heritage site by UNESCO on 14th December 1992 as Angkor Wat-Heritage of Humanity and World Wonder. It is the largest religious monument in the world and is also the representation of the country as a whole as it appeared on Cambodia flags. There are a lot of stories narrated on the walls differently, and the whole temple itself surrounds by water. Nowadays, there has been the collapse of bricks of some, some are forbidden to climb to, and some stairs are replaced (put over) wooden stairs to climb to. In 2014, Khmer New Year (Sangkranta) has been largely celebrating in Siem Reap province near the temple and been called Angkor Sangkranta.
