Angkor Wat was first a Hindu, later a Buddhist, temple complex in Cambodia. It is the largest religious monument in the world.
Angkor Wat combines two basic plans of Khmer temple architecture: the temple-mountain and the later galleried temple, based on early Dravidian architecture, with key features such as the Jagati.
The temple was built by the Khmer King Suryavarman II in the early 12th century in Yaodharapura the capital of the Khmer Empire, as his state temple and eventual mausoleum.
The modern name, Angkor Wat, means "Temple City" or "City of Temples". The temple is admired for the grandeur and harmony of the architecture, its extensive bas-reliefs, and for the numerous devatas adorning its walls.
Choeung Ek is the best-known of the sites known as The Killing Fields, where the Khmer Rouge regime executed over one million people between 1975 and 1979.
It is the site of a former orchard and mass grave of victims of the Khmer Rouge - killed between 1975 and 1979 - about 17 km south of Phnom Penh, Cambodia.
Today, Choeung Ek is a memorial, marked by a Buddhist stupa. The stupa has acrylic glass sides and is filled with more than 5,000 human skulls. Some of the lower levels are opened during the day so that the skulls can be seen directly. Many have been shattered or smashed in.
