These twin ponds are one of the most beautiful works of art during the ancient Anuradhapura kingdom. The garden which separates these 2 ponds is 18½ ft (5.6 m). The larger of this pair is 132 ft in length and 51 ft in breadth (40 by 15.5 m), while the smaller is 91 feet long, the breadth is the same (28 by 15.5 m). The depth of the smaller pond is 14 feet (4.3 m) and the larger pond is 18 feet (5.5 m).
The faces of the pools were cut granite slabs which includes the bottom and the sides of the pool. A wall was also built around the pool which encloses the compound. Flights of steps are seen on both ends of the pool decorated with punkalas, or pots of abundance and scroll design. Embankments were constructed to enable monks to bathe using pots or other utensils. Water to the pools were transferred through underground ducts and filtered before flowing to the pool and in a similar fashion the water was emptied.
Dr. Senerath Paranavithana was actively involved in the restoration of the ponds, in which small figures of fish, a conch, a crab and a dancing woman were found in the bottom.
