Angkor boasts some of the largest religious monuments ever built as it is known as the “City of God-Kings“. Many of these temples and monuments are under conservation and restoration funded by international organizations that include UNESCO, France, Germany, Japan and the U.S..

Preah Khan or “Sacred Sword ” is one of the largest complexes and is a maze of vaulted corridors, fine carvings and stonework. It served as the temporary residence of the King while Angkor Thom was under construction.

The Temples of Rolous (namely Lolei, Bakong , and Preah Ko) are among the earliest temple complexes built in the late 800s by the Khmers and is the dawn of classical art at Angkor.
