Unbelievable!

The temple compound of Angkor Wat is indeed beyond imagination! (it was built by a famous Cambodian king to celebrate his success.)
Built of perfectly fit stone, It is about a mile long and a mile wide with a maximum height of about 200 ft from the ground. It is surrounded by a double moat to symbolize two famous rivers in India.
It has a carved pictorial history that wraps a kilometer around the main building (!!!).
