West Baray reservoir begun at Angkor
1021
Suryavarman I ordered the construction of an immense artificial reservoir eight kilometers long and two kilometers wide at the Khmer capital, a feat of hydraulic engineering that dwarfed anything in contemporary Europe. The West Baray stored monsoon floodwaters for dry-season irrigation, sustaining the rice agriculture that fed Angkor's vast population and its armies of temple builders.
