Kuttam Pokuna or the twin ponds are another hydro logic engineering marvels of the ancient Sri Lanka. These two ponds belong to the
Abayagiri aramic complex and probably been used by the monks for bathing. The
origins of these ponds are not known but it is thought to have been built
during the reign of King Aggabodhi I (575-608).
The smaller pond (the northern) one has been constructed
first and the larger one at a later stage. They are connected through a
pipeline at the bottom. The northern pond is 91 feet (28 metres) long and the
other 132 feet (40 meters) .
Water to these ponds have been supplied through underground
pipelines and the water is sent through several filtering chambers before it
falls on the northern pond through a mouth of a dragon. The water from both
ponds is drained from a small outlet in the smaller northern pond.
Though the underground pipelines are no more, some of these
filters can still be seen.
