Eth Pokuna ( Elephant pond) – Anuradhapura
Eth Pokuna, also called Elephant pond, is a massive artificial pond situated close to Lankaramaya Anuradhapura. This pond is 159 meters long, 52.7 meters crossed, and 9.5 meters in-depth, with 75,000 cubic meters of water holding volume.
The water to this pond has been provided from the Periyamkulama Tank through a system of underground waterways, and you still can see part of the water lines built out of rock slabs.
Those underground waterways still work after so many hundreds of years, and in 1982 after a hefty rainy season, you could see water pouring through these channels from the Periyamkulama tank.
This tank has been utilised by the Abayagiri monastery monks, who amounted to over five thousand priests.
