"Kuttam Pokuna' - Twin ponds, Anuradhapura, Sri Lanka, 6th to 8th Century AD.
"Kuttam Pokuna" or the twin ponds are another hydrologic engineering
marvel of 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 meters) 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, you can see 4 levels of filtering of the water before it enters the ponds.

For symmetry and beauty, constructed out of granite, 1500 years ago, it is hard to beat.

Dr. Senarath 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.

Jetawanaraamaya and Ruwanwelisaeya, Anuradhapura, Sri Lanka.
The
tallest brick structure and the widest Chaitya of the ancient world -
Jethawanaaramaya and Ruwanvelisaeya, Anuradhapura, Sri Lanka.
Jethawanaaramaya stupa
located in the ruins of Jetavana in the sacred world heritage city of Anuradhapura, Sri Lanka. Mahasena of Anuradhapura (273–301) initiated the construction of the stupa following the destruction of the mahavihara. His son Maghavanna I completed the construction of the stupa.[1] A part of a sash or belt tied by the Buddha is believed to be the relic that is enshrined here.
Design and construction[edit]
As the largest ancient stupa constructed and one of the tallest ancient structures in the world, the structural ingenuity and engineering skills employed for the construction are significant. The foundations of the structure were 8.5m deep and the size of the structure required bricks which could withstand loads of up to 166 kg. The solid foundation lay on bed-rock and the dome was constructed of full and half bricks and earth fill, the unique shape of a perfect ellipsoid allowed for stress and thus allowed the construction of the large structure.[6] The Mahavamsa describes the foundation laying, where fissures were filled with stones and stamped down by elephants whose feet were protected with leather bindings. The bricks used for the construction were a significant development of ancient Sri Lankan engineering, the bricks used for Jetavanaramaya had a composition of 60 percent fine sand and 35 percent clay, the bricks could withstand 281 kg/in2.[6] Linear elastic finite element analysis under self weight produced a maximum compressive stress of 839 kPa at the bottom centre, thus the maximum stress in the dome is ten times less than what the bricks could withstand.[7]
Finely crushed dolomite lime stone, sieved sand and clay provided the bonding material for the bricks. The clay employed was pliable and thus accommodates movement within the structure. One of the sides of the brick was roughened to trap the bonding slurry thus limiting lateral movement.[6] The stupa was then covered with lime plaster; the plaster used contained seashells, sugar syrup, egg whites, coconut water, glues, oils, plant resin, sand, clay and pebbles. The plaster also provided waterproofing for the structure. The Mahavamsa also mentions the use of copper sheets over the foundation and arsenic dissolved in sesame oil to prevent insect and plant intrusions inside the stupa.[6] It is estimated that Jetavanaramaya took 15 years to complete and would have required a skillful workforce of hundreds, including brickyard workers and bricklayers, and stonemasons.[6]

Ruwanveli Saeya
It was built by King Dutugemunu c. 140 B.C., who became lord of all Sri Lanka after a war in which the Chola King Elara, was defeated. It is also known as Mahathupa, Swarnamali Chaitya, Suvarnamali Mahaceti (in Pali) and Rathnamali Dagaba.
On such a full-moon day King Dutugemunu had the inscribed stone pillar that was erected by King Devanampiya Tissa, removed; had the site leveled; had it dug to a depth of seven cubits; had round stones spread there by warriors; and had the stones broken with hammers;
then he had them stamped down by elephants; fine clay was brought from the Himalayas by Arahant novices, spread over the layer of stones; had bricks laid over the fine clay, rough plaster over the bricks, quartz over the rough plaster, a network of iron over the quartz, fragrant clay over the network of iron, white stones over the fragrant clay, rock-crystal over the white stones, and slabs of stones over the rock-crystal. Then he had mercury, resin of the wood-apple, and fine clay mixed together; had these spread over the slabs of stones; and had bronze sheets eight inches thick laid over these.
He had arsenic and sesame oil mixed together; had these spread over the bronze sheets; and had silver sheets four inches thick laid over these.
When the king had thus built and completed the foundation of the Great Stupa, he arranged that the foundation stone should be laid on the full-moon day of the month of Āâsà ëha (June–July).

Stone bridge on the old Avissawella to Yatyanthota railway line, Sri Lanka.
This railway line has been disused from 1938. A house has been built on the bridge now.
