Angkor Wat is a large and ornate 900 year old abandoned city of stone temples located deep in the jungles of Cambodia, re-discovered in 1860 by a French explorer.  The city is the size of London, and it was larger and in many ways more advanced than any European city at its time.  Scholars have been able to decipher its writings due to some of it being written in sanskrit, which has revealed the city’s history.  In 1431 the city was sacked by people from Thailand who enslaved many of its residents, which soon led to the area being abandoned.  This well-made documentary recreates what the area looked like at the time.
