Angkor Wat (or Angkor Vat) is a temple at Angkor, Cambodia, built for king Suryavarman II in the early 12th century as his state temple and capital city.

The largest and best-preserved temple at the site, it is the only one to have remained a significant religious centre—first Hindu, then Buddhist—since its foundation. The temple is the epitome of the high classical style of Khmer architecture.

It has become a symbol of Cambodia, appearing on its national flag, and it is the country's prime attraction for visitors. 

According to Guinness World Records, it is the largest religious structure in the world.

With the decline was she slowly abandoned until it was forgotten by all.  A canopy of green closed over and only villagers existed.  Hundreds of years silently passed with the outside world finally returning in the late 1800s.  During the 20th century Beng Mealea was once again a stop-off point for travelers on their way to the Great Preah Khan.  By 1958 the diligent French had cleared away the undergrowth, too late, for the years of conflict were coming.  Few dared to venture afar and again did Beng Mealea sink back to the forest.

Reports of Beng Melea began circulating in the late 1990s.  A few intrepid souls brought back tales of being escorted by villagers to a lost temple buried under the vegetation.  Credible tales, but photos brought back as evidence were murky and difficult to verify.  Little light passed through the canopy and vegetation covered it all.  Still, more visitors made the effort and once what was a journey out of David Livingston became a day-trip from he town.

Today itself Beng Mealea itself has been demined although the surrounding area is clearly marked off-limits.  The local villagers are very kind and friendly however.  Beng Mealea lies 2 hours from Siem Reap by a rutted road and most difficult to get to in the monsoon season.

Preah Ko – The Sacred Ox – was the first temple to be built on the site of Hariharālaya (presently Roluos), south-east of the main group of temples at Angkor, Cambodia. It was built by Indravarman I in the late 9th century.
