Step into the largest religious complex on earth, the temples of Angkor. Started as a mausoleum for a 12th-century Khmer king, it was expanded into a representation of the celestial world.

The proportions here are astounding. The so-called “the city of temples” reveals itself in alabyrinth of carved temples, galleries and stairways that stretch over hundreds of acres.

Everywhere exquisite bass-reliefs (also called "bas-reliefs") bring the stories of the Hindu andBuddhist legends to life. Colorful history of different regimes and cultural influences has resulted in today's sprawling complex, full of unique corners.

The main temple of Angkor Wat, with its lotus bud-like towers, is a pinnacle of Khmer artistry, and the causeway approach brings its colossal presence into focus.

North of Angkor Wat is the walled city of Angkor Thom, where visitors enter under the watchful gaze of the gate's stone visage. Carved faces give the temples here unique personality.

Many parts of the Angkor complex like the monastery of Ta Prohm, have beenreclaimed by the surrounding vegetation. Here the big jungle is festooned throughout the stonework, a modern day vision of the mysterious lost city that captured the imagination of 19th-century French explorers.

Like many ancient structures, Angkor is threatened by exposure to the elements. In 1992, the complex was designated a World Heritage Site by UNESCO. And in the years since, the international community has come together to preserve this cultural treasure for future generations.
