West Baray

West Baray

Guide Location: Outside the west gate of Angkor Thom, approximately 11 km northwest of Siem Reap. Construction Period: Mid-11th century. Function: Reservoir. Introduction: Stretching 8 km in length and 2.3 km in width, it is the largest artificial reservoir in world history. Nowadays, it is mostly visited by locals who play on the sandy shores, making it feel much like a seaside beach. During the 9th to 12th centuries, the Khmer Empire invested heavily in hydraulic engineering, constructing a grand water management system centered around the East Baray, West Baray, North Baray, Roluos Baray, Royal Bathing Pool, the moats of Angkor Wat and Angkor Thom, along with thousands of smaller ponds and canals. Based on the region’s distinct dry and rainy seasons, the system efficiently collected and redistributed river water to irrigate farmlands, while also supporting urban and temple water supply, drainage, defense, and transportation needs. Thanks to this advanced irrigation network, the Khmer were able to achieve double or even triple rice harvests a year as early as 1,000 years ago. These hydraulic projects can be regarded as wonders on par with the architectural and bas-relief artistry of Angkor. However, as the empire declined and the infrastructure fell into disrepair, devastating floods eventually struck, dealing a fatal blow to Khmer civilization.
