Sri Lanka has a rich written history which dates back to 600 B.C, and by folklore we understand that the island had an older glorious past.

Such a history has bestowed many heritage sites and cultural values to the modern Lanka. There are different eras that a historian can choose to linger on, from the prehistoric caves of Balangoda to the sites of Ramayana, ancient irrigation systems and colonial architecture.

Anuradhapura is one of the ancient capitals of Sri Lanka, famous for its well-preserved ruins of ancient Sri Lankan civilization. It was 3rd capital of the Kingdom of Rajarata after Tambapanni and Upatissa Nuwara.

The city, now a UNESCO World Heritage Site, is one of the oldest continuously inhabited cities in the world , It is believed that from the 4th century BC, it was the capital of the Sinhalese until the beginning of the 11th century AD.

While Vijayabahu's victory and shifting of kingdoms to the more strategic Polonnaruwa is considered significant, the real "Hero of Polonnaruwa" of the history books is actually 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 so adamant that no drop of water falling from heavens was to be wasted, and each was to be used toward the development of the land; hence, irrigation systems that are 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.

Dambulla is thought to be inhabited from as early as the 7th to 3rd century BC. Statues and paintings in these caves date back to the 1st century BC. But the paintings and statues were repaired and repainted in the 11th, 12th, and 18th century AD. The caves in the city provided refuge to King Valagamba (also called Vattagamini Abhaya) in his 14 year long exile from the Anuradapura kingdom. Buddhist monks meditating in the caves of Dambulla at that time provided the exiled king protection from his enemies. When King Valagamba returned to the throne at Anuradapura kingdom in the 1st century BC, he had a magnificent rock temple built at Dambulla in gratitude to the monks in Dambulla.

Sigiriya consists of an ancient castle built by King Kasiappan during the 5th century. The Sigiriya site has the remains of an upper palace sited on the flat top of the rock, a mid-level terrace that includes the Lion Gate and the mirror wall with its frescoes, the lower palace that clings to the slopes below the rock, and the moats, walls, and gardens that extend for some hundreds of meters out from the base of the rock.

Sigiriya is a UNESCO listed World Heritage Site. It is one of the best preserved examples of ancient urban planning.[2] It is the most visited historic site in Sri Lanka.

Koneswaram temple of Trincomalee or Thirukonamalai Konesar Temple - The Temple of the Thousand Pillars and Dakshina-Then Kailasam is a classical-medieval Hindu temple complex in Trincomalee, a Hindu religious pilgrimage centre in Eastern Province, Sri Lanka.

Galle Fort, in the Bay of Galle on the southwest coast of Sri Lanka, was built first in 1588 by the Portuguese, and then extensively fortified by the Dutch during the 17th century from 1649 onwards. It is a historical, archaeological and architectural heritage monument, which even after more than 423 years maintains a polished appearance, due to extensive reconstruction work done by Archaeological Department of Sri Lanka.
