Kuttam Pokuna are well preserved old bathing tanks or ponds in Sri Lanka. This pair of ponds was built by the Sinhalese in the ancient Anuradhapura Kingdom. They form part of the Abhayagiri vihāra complex and are an example of the works in the field of hydrological engineering, architecture and art of the ancient Sinhalese.

A swimming pool, swimming bath, wading pool, paddling pool, or simply pool, is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground or built above ground, and may be found as a feature aboard ocean-liners and cruise ships. In-ground pools are most commonly constructed from materials such as concrete, natural stone, metal, plastic, composite or fiberglass, and can be of a custom size and shape or built to a standardized size, the largest of which is the Olympic-size swimming pool.
