Why in news?
Archaeologists working at the Pool No. 11 site in Angkor Thom, Cambodia, have uncovered remnants of a sophisticated hydraulic system dating to the late 12th century. Excavations revealed drainage structures, stone slabs and carvings depicting boats and aquatic scenes, all linked to a royal pool used by King Jayavarman VII’s court. The discovery will aid restoration of the ancient water network and improve water management for visitors.
Background
Angkor Thom (“Great City”) was the last and largest capital of the Khmer empire. Built by King Jayavarman VII in the late 12th century, the city covers about 9 square kilometres and was enclosed by a square wall 8 metres high and 3 kilometres long on each side. Beyond the walls a broad moat provided defence and water storage. Major temples within the city include the Bayon (famous for its smiling stone faces), Baphuon, Phimeanakas and the palace terraces. Elaborate gateways in each cardinal direction are adorned with huge stone faces thought to represent the bodhisattva Avalokiteshvara or the king himself. The city’s canal and reservoir system ensured irrigation, transport and ceremonial functions.
Recent findings
- Hydraulic engineering: The excavated pool measures roughly 65 metres by 30 metres. Beneath its floor archaeologists found stone channels and vents designed to control water flow and prevent flooding. Sediment layers indicate that the pool dates to the late 12th century.
- Carvings and artefacts: Stone slabs around the pool bear bas‑relief carvings of boats, musicians and aquatic life, offering glimpses into the daily life and rituals of the Khmer royal court.
- Preservation plans: The Angkor International Center for Research and Documentation plans to restore the hydraulic system, revive its biodiversity and ensure that water drains properly during heavy rains, improving the site’s resilience for tourists.
Significance of Angkor Thom
Angkor Thom represents the pinnacle of Khmer architecture and urban planning. Its layout, cosmology and artistry reflect Hindu‑Buddhist influences and the political power of Jayavarman VII. The newly uncovered hydraulic features add to our understanding of how the city’s residents managed water for agriculture, ceremonies and daily living. Maintaining these systems is essential for conserving the UNESCO World Heritage site and sustaining tourism in the Angkor region.
Conclusion
The Pool No. 11 excavation highlights the ingenuity of Khmer water engineers and enriches our appreciation of Angkor Thom’s urban design. By restoring and studying these systems, Cambodia can both preserve its heritage and support sustainable tourism.
