Angkor Wat ("City Temple") is a vast temple complex near Siem Reap, about 200 miles from the capital of Phnom Penh in Cambodia. Built in the 12th century by the king of the prosperous Khmer empire, Angkor Wat was built as a royal temple dedicated to a Hindu deity.
After the city of Angkor fell to invaders, Angkor Wat receded into the jungle but continued as a Buddhist temple and a pilgrimage site over the centuries.
Angkor Wat is the best preserved example of Khmer architecture in Cambodia and is so grand in design that some rank it among the seven wonders of the world. It appears on the Cambodian national flag, a very rare instance of a flag incorporating an image of a building.
A one day pass will cost you 20 dollars USD. In Cambodia specially Angkor Wat for females you need to dress pants or jeans or well covered dresses otherwise you are not allowing to enter a certain temples because to the Khmer they are sacred and spiritual places. I was heard the story that a long time ago the females would not allow to enter into the temples but now with $USD 20 dollars you can enter into the temples with the above conditions.
