While Vijayabahu's victory and shifting of Kingdoms to the more strategic Polonnaruwa is considered significant, the real Polonnaruwa Hero of the history books is actually his grandson, Parakramabahu I. It was his reign that is considered the Golden Age of Polonnaruwa, when trade and agriculture flourished under the patronage of the King, who was adamant that no drop of water falling from the heavens was to be wasted, and each be used toward the development of the land; hence, irrigation systems far superior to those of the Anuradhapura Age were constructed during Parakramabahu's reign, systems which to this day supply the water necessary for paddy cultivation during the scorching dry season in the east of the country. The greatest of these systems, of course is the Parakrama Samudraya or the Sea of Parakrama, a tank so vast that it is often mistaken for the ocean. It is of such a width that it is impossible to stand upon one shore and view the other side, and it encircles the main city like a ribbon, being both a defensive border against intruders and the lifeline of the people in times of peace. The Kingdom of Polonnaruwa was completely self-sufficient during King Parakramabahu's reign.

Historical records suggest that Kandy was first established by the King Wickramabahu (1357-1374 CE) near the Watapuluwa area, north of the present city, and named Senkadagalapura at the time, although some scholars suggest the name Katubulu Nuwara may also have been used. The origin of the more popular name for the city, Senkadagala, could have been from a number of sources. These include naming after a brahmin named Senkanda who lived in a cave near the city, after a queen of King Wickramabahu named Senkanda or after a colored stone named Senkadagala.

Kingdom of Kandy In 1592 Kandy became the capital city of the last remaining independent kingdom in the island after the coastal regions had been conquered by the Portuguese. Several invasions by the Portuguese and the Dutch (16th, 17th and 18th century) and later by the British (most notably in 1803) were repelled. Portuguese invasions in the 16th century and 17th century were entirely unsuccessful.

Nuwara Eliya: The town was founded by Samuel Baker as a hill retreat for the British during the colonial era, where typical English pastimes including golf ,fox hunting, polo and cricket were played.
Although the town was founded in the 19th century by Englishmen, the site was frequently visited by native Sinhalese travellers. It has also been an area of pre-historic human beings as recent archaeological findings confirm.[citation needed]

Many of the buildings retain features from the colonial period, and even new hotels are often built and furnished in the colonial style. The Hill Club is one of the best preserved hotels, and charges admission for non-residents who wish to wallow in its nostalgia. Many private homes still maintain their old English-style lawns and gardens.
