Siem Reap is one of the most famous tourism destination in the world because of its incredible temples of Angkor and very rich culture of ancient Khmer Empire. Most visitors wish to come to Cambodia to adventure with the ruins temples of Khmer Empire and experiencing with today Cambodian people.
The southern coastal strip has never been of importance for the Cambodian economy. It is separated from the central plain by difficult terrain. The Mekong river has always been the economical conduit of Cambodia.
Angkor Wat lies 5.5 km north of the modern town of Siem Reap, and a short distance south and slightly east of the previous capital, which was centred at Baphuon. It is in an area of Cambodia where there is an important group of ancient structures. It is the southernmost of Angkor's main sites.
The initial design and construction of the temple took place in the first half of the 12th century, during the reign of Suryavarman II (ruled 1113 – c. 1150). Dedicated to Vishnu, it was built as the king's state temple and capital city. As neither the foundation stela nor any contemporary inscriptions referring to the temple have been found, its original name is unknown, but it may have been known as Vrah Vishnulok after the presiding deity. Work seems to have ended shortly after the king's death, leaving some of the bas-relief decoration unfinished. In 1177, approximately 27 years after the death of Suryavarman II, Angkor was sacked by the Chams, the traditional enemies of the Khmer. Thereafter the empire was restored by a new king, Jayavarman VII, who established a new capital and state temple (Angkor Thom and the Bayon respectively) a few kilometres to the north.
In the late 13th century, Angkor Wat gradually moved from Hindu to Theravada Buddhist use, which continues to the present day. Angkor Wat is unusual among the Angkor temples in that although it was somewhat neglected after the 16th century it was never completely abandoned, its preservation being due in part to the fact that its moat also provided some protection from encroachment by the jungle.
One of the first Western visitors to the temple was Antonio da Magdalena, a Portuguese monk who visited in 1586 and said that it "is of such extraordinary construction that it is not possible to describe it with a pen, particularly since it is like no other building in the world. It has towers and decoration and all the refinements which the human genius can conceive of". However, the temple was popularised in the West only in the mid-19th century on the publication of Henri Mouhot's travel notes. The French explorer wrote of it: "One of these temples—a rival to that of Solomon, and erected by some ancient Michelangelo—might take an honourable place beside our most beautiful buildings. It is grander than anything left to us by Greece or Rome, and presents a sad contrast to the state of barbarism in which the nation is now plunged."
