Why visit Basawakkulama Wewa

• Earliest Recorded Tank in Sri Lanka: Basawakkulama Wewa is the first reservoir mentioned in Sri Lanka’s recorded history (Mahavamsa). It was initially established by Prince Anuradha near his settlement, which became Anuradhapura.

• 2,500 Years of Continuous Service: Despite being built roughly 2,500 years ago, the tank continues to supply water to the modern city of Anuradhapura, serving as a powerful testament to the advanced engineering skills of ancient Sri Lankans.
• Symbol of Ancient Urban Planning: King Pandukabhaya enlarged the original tank to provide a reliable water supply for his enlarged capital city of Anuradhapura, demonstrating a thoughtful design to maximize efficiency based on the catchment area.
