Dagobas or Stupas

The dagobas or stupas of Sri Lanka are significant to the architectural and engineering development in the island, stupas designed and constructed in Sri Lanka are the largest brick structures known to the pre-modern world.

 were in the shape of a paddy heap. Other shapes such as the bubble(Ruwanweli), pot and bell developed later, it is suggested that the stupa at Nadigamvila was in the shape of an onion.

An ornamented vahalkada was added to stupa design around the second century; the earliest is at Chaitya. The four vahalkadas face the cardinal points, ornamented with figures of animals, flowers, swans and dwarfs. The pillars on either side of the vahalkada carry figures of lions, elephants, horses or bulls, depending on the direction of the structure.

The stupas were covered with a coating of lime plaster

 used small pebbles, crushed seashells mixed with lime and sand were used in the stupas from the fifth to twelfth centuries.

Vatadage

The vatadage is considered to be one of ancient Sri Lanka's most prolific architectural creation, the design represented a changing perspective of stupa design independently within the island. Early provincial vatadages have been in the form of a square later it developed in to a circular form enclosing the dagoba. Polonnaruwa
Polonnaruwa Vatadage
The Polonnaruwa Vatadage is an ancient structure dating back to the Polonnaruwa period of Sri Lanka. It is believed to have been built during the reign of Parakramabahu I to hold the tooth relic of the Buddha, or during the reign of Nissanka Malla to hold the alms bowl used by the Buddha...

, Medirigiriya and Tiriyaya vatadages still have their circles of slender, graceful pillars. The vatadage roof was of a sophisticated design unique to ancient Sri Lanka, it is a three-tiered conical roof, spanning a height of 12–15 m, without a centre post, and supported by pillars of diminishing height. The weight was taken by a ring beam supported on the inner row of stone columns, the radiating rafters met in a cartwheel-like design. The ornemental qualities of the Polonnaruwa vatadage is highly valued, scholars argue the Pollonnaruwa vatadage to represent the best architecture work of the Polonnaruwa period.

Meditation houses

. The stone masonry is also of a very high standard. The basements of these buildings were constructed of monumental blocks of stone, cut to different sizes, carefully dressed and very finely fitted together. The bridge connecting the two platforms was formed out of a single slab of stone. Some such slabs measured 15 feet (5 m) by 13 feet (4 m). The sides have been cut with precision where the joints between the slab and the stone moulding of the platforms are hardly perceptible.

Vaulted roof shrine
The brick shrine with vaulted roof, as seen at Thuparama, Lankatilaka and Tivanka Pilimage, is also considered unique to Sri Lanka. The Thuparama is almost intact today and gives an idea of the manner in which the vaulted roof was created. The principles of the true arch were known to the ancient Sri Lankans, but the horizontal arch was considered a safer method of construction.

Sky scrapers

The nine-storied Loha maha paya (3rd century BCE) would have been an elegant building. It had an exposed wooden frame supported on stone pillars. It was plastered in white, with shining copper roof tiles and a pinnacle

 at its apex. It had lightning conductors or chumbakam made of amber and tourmaline. Its rafters were made of talipot palm. It rose to a height of 162 feet (49 m) and had approximately 179316 square feet (16,659 m²) of floor space. It could seat 9000 monks. Roland Silva remarked in 1984 that such an extensive floor space would stagger the designers in Sri Lanka "even today". The dominant element in these buildings, was the tiled roof supported by timber beams and rafters. The roofs were tiled, from as early as the third century BCE, with red, white, yellow, turquoise and brown tiles. There were also tiles made of bronze

, and Parakramabahu's palace in Panduvasnuvara near Hettipola, when he was ruling over Malaya rata.

Ground plan
All the palaces had the same ground plan. Each was set in a rectangular area enclosed by galleries with an entrance from the east. A spacious courtyard in front acted as a reception room, where sitting was not allowed. A flight of steps led to a central building where there was an imposing pillared hall with a dais

 at the end. Around the royal complex were over fifty small cells, in two or three rows. The hall in Nissanka Malla's palace was 133 feet (41 m) by 63 feet (19 m). The floors of the upper storey in Parakramabahu's palace were of concrete. Panduwasnuwara palace had good provision for ventilation and there were soakage pits for drainage.

Rock Palaces

There was a palace on top of the Sigiriya

 rock as well. The outlines of the total layout and several detailed features are still visible. There was an upper palace that ran parallel to the lower one, but at a much higher elevation. It had a viewing gallery. The innermost royal abode, which was originally a storeyed structure, had a magnificent 360 degree view of the city gardens and countryside below. There was a series of successive courtyards, chambers, and terraces connected by stairs and paved pathways.

Pool Design

Kumara Pokuna in Polonnaruwa provides one of the best examples of the construction of a royal bath. A flight of long narrow steps led to an oblong shaped pond that had graduated gangways. The water was conducted by underground pipelines from the canal nearby and led into the bath by two makara gargoyles. A stone water lock acted as water locking valve and an exit for used water. There is also a now-ruined changing room.

Audience halls

Parakramabahu's council chamber was a three-tiered oblong structure built on a broad terrace, facing north, and consisted of an entrance provided with two flights of steps, having a gangway in between at ground level. The pillars in the council halls at Polonnaruwa are square at the bottom, octagonal in the middle and square again at the top.

Hospitals

Some idea of hospital architecture can be inferred from the monastic hospitals at Mihintale

. There was an inner and outer court and the rectangular inner court had a series of cells, toilets and bath, with an exit at one end. One cell had a medicinal bath. Alahena had long dormitories instead of cells. The outer court accommodated a refectory, a hot water bath, storerooms and dispensary. A wall cordoned off the hospitals. The provision of two open courts in addition to windows ensured maximum ventilation and free circulation of air within the building itself.

Houses

A house dated to 450 BCE, built of warichchi (wattle and daub

s. The doors had keys, locks, and hinges. The houses had compounds or courtyards and balconies. There were separate rooms for pounding paddy, a storeroom or atuva for paddy, and sheds for keeping chariots. Latrines are also mentioned. All houses however had small kitchens.

Design and construction

Architects
There were architects to attend to the built environment. A cave inscription refers to a "city architect". Building was done scientifically, using superior instruments. For example, some stone slabs were so precisely cut that the joints are hardly visible and nothing could be inserted between the slabs. Ashley de Vos points out that this would require sophisticated instruments even today. Lifting and placing of slender stone slabs, twenty feet long, would have needed knowledge of structural mechanics. De Vos also suggests that Sri Lanka may have had the first pre-fabricated buildings in the world. Some sections of the monastic buildings were prepared separately and then fitted together.

Artistry

There was artistry in addition to technical finesse. This is illustrated in the elegantly executed stone pillars dating from the eighth century. They are in various designs. The lotus-stalk pillars of the Nissanka Latha Mandapaya
Nissanka Latha Mandapaya

Water

 had a graduated series of ponds going from shallow to deep. Essential facilities were not forgotten: the Nandana Gardens had a large gleaming bathroom.

Air cooling
There was an air cooling method in the ancient period. A dried buffalo skin was fixed above the roof of the building. Water dripped onto it from several pipes, creating the effect of rain and sending in a cooling breeze. Pictures on walls were changed according to the season; cooling pictures for the hot season and warming pictures for the cool season.

Building materials

Builders worked with a variety of materials, such as brick, stone and wood. Corbel
Corbel
In architecture a corbel is a piece of stone jutting out of a wall to carry any superincumbent weight. A piece of timber projecting in the same way was called a "tassel" or a "bragger". The technique of corbelling, where rows of corbels deeply keyed inside a wall support a projecting wall or...

led and circular brick arches, vaults and domes were constructed. Rock faces were used as supporting walls for buildings. The platform carrying the mirror wall at Sigiriya and the brick flight of steps stand on steep rock. Around the sixth century, the builders had moved from limestone to the harder gneiss
Gneiss
Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks.-Etymology:...

. The vatadage in Polonnaruwa had walls that were constructed of stone to the height of the upper storey. The lowest step of an imposing granite stairway that led to the upper storey of Parakramabahu's palace can still be seen. Meticulous detailing had been done in the leaf huts used by the forest monks of the 5th century CE.

Timber

It is important to note, however, that the ancient architecture was not stone architecture. The stone remains seen are misleading. It was primarily timber architecture, with mud or masonry walls. There were sophisticated wooden buildings from the 3rd century. Sigiriya had an elaborate gatehouse made of timber and brick masonry with multiple tiled roofs. The massive timber doorposts remaining today indicate this.

The timber carried the load. Frames were made out of whole trunks of trees. The gatehouse at the eastern entrance to Anuradhapura

built in the 4th century BC used whole trees. The palaces at Polonnaruwa and Panduwasnuwara show vertical crevices in the brickwork where wooden columns, consisting of entire trunks of trees, carried the load of the upper floors and roof. These openings still retain the spur stones upon which the wooden column once stood.

The text of the Manjusri silpa describes methods for the cutting and seasoning of wood. Mature trees were selected and cut in the new moon when the sugar content in timber was lower, so that destructive woodboring insects were not attracted to the timber. The stone remains show that sound carpentry techniques were employed. The axe, adze and chisel were the common tools used in timber work. Saddharmarat-navali mentions two practices of carpentry. Oil was applied to timber to prevent decay, and wood was heated to straighten it.
