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 most magnificent specimen of bathing tanks is the pair known as Kuttam Pokuna at Anuradhapura, near Abhayagiri Monastery. The sides and the bottom of the ponds were faced with well cut granite slabs. Round the pond is a magnificent wall. Leading to the pond are a beautiful flight of steps on both sides, and decorated with "punkalas" and scroll design. There were underground ducts bringing water into these ponds and others emptying them. A wall is built to enclose the ponds, and inside it is a small compound.
