Ancient Constructions of Sri Lanka

The earliest evidence of cave temples are found in Mihintale. A unique feature in these caves was the use of a drip ledge carved along the top edge of the rock ceiling which stopped rain water running into the cave. With time doors, windows and walls of brick or stone were added. The roof and walls were plastered white and finished with decorative paintings, these are evident in the cave temples of Dambulla. Chipped material of the rock packed underneath the clay finished floor.
Cave complexes of Dambulla and Situlpahuwa contained 80 caves each, The Kaludiya Pokuna, Mihintale cave temple is constructed with brick walls, granite window openings, and ceilings. The Gal vihara, Polonnaruwa and the cave temples of Dambulla were initially constructed as cave temples, later on the cave temples were converted to image houses.

Dagobas or Stupas

The dagobas or stupas are distinctive for many reasons. They are probably the largest brick structures known to the pre-modern world. Demala Maha Seya, which was never completed, had a circumference of 2,011 feet (613 m). Jetavanaramaya is the largest stupa constructed in any part of the world. It is over 120 metres in height and has a diameter of 367 feet (112 m). The foundations are 28 feet (9 m) deep. It needed bricks that could bear the load of 368 pounds. Jetavanarama was the third tallest building in the ancient world. Abhayagiri Dagaba (370 ft) ranked fifth and Ruwanwelisaya (300 ft) came seventh (the first, fourth and sixth places were held by the Pyramids of Giza).

The construction of a dagoba was considered an act of great merit. Dagobas were built to enshrine relics. They were constructed according to strict specifications. Entrances to stupas were laid out so that their centre lines pointed to the relic chambers. There was only one relic chamber initially, but a number of additional relic chambers were introduced when the stupas were rebuilt.
The dagoba is admired today for its structural perfection and stability. Engineers who examined Jetavanaramaya in the 1980s said that its shape was ideal for the materials used. Stupas such as Jetavanarama, Abhayagiri, Ruvanveli and Mirisaveti Stupa were initially in the shape of a paddy heap. Other shapes such as the bubble, pot and bell developed later. It is suggested that the stupa at Nadigamvila digamvila was in the shape of an onion.
An ornamented vahalkada was added to the stupa around the second century; the earliest is at Chaitya. The four vahalkadas face the cardinal points. They are 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 bricks were bonded together using a clay slurry, called butter clay or navanita mattika. This was composed of finely crushed dolomite limestone mixed with sieved sand and clay.
The stupa was thereafter covered with a coating of lime plaster. This was sometimes ten inches thick. There was a range of plasters, using different combinations of materials. The items used included lime, clay, sand, pebbles, crushed seashells, sugar syrup, white of egg, coconut water, plant resin, drying oil, glues and possibly even the saliva of white ants. Some of these items are mentioned in the Mahavamsa. The fine plaster at Kiri Vehera (2nd century) used small pebbles. Crushed seashells mixed with lime and sand were used in the stupas of the fifth to twelfth centuries. Expensive plasters were used sparingly, for specific purposes such as waterproofing.
Stupas in other countries have been struck by lightning, but not in Sri Lanka. Mahavamsa speaks of lightning protection for the stupa. The conical metal cap and its vajra at the top of the dagoba were supposed to have earthing properties. The Mahavamsa also refers to laying a sheet of copper over the foundation and applying arsenic dissolved in sesamum oil on this sheet. This would have kept out white ants and helped prevent plant life growing inside the stupa.

Ramparts of the Galle fort

With the arrival of colonials to Sri Lanka, they established their own form of architecture to the island. This is evident in the architecture of the period as well as in forms on influence in modern architecture. Very few buildings of the Portuguese era survives, however many building from the Dutch era could be found on the coastal parts of the island. For example, the Old Town of Galle and its Fortifications built by the Dutch in the year 1663 make up a UNESCO World Heritage Site.

The Neo-baroque style Old Parliament Building, which is now the Presidential Secretariat

Many important historic buildings were those built by the colonial governments. These were often built in one or another European architectural style, which was in fashion at the time, such as the Palladian, Renaissance, or Neo-classical styles.
