Polonnaruwa was the second capital of Sri Lanka after the destruction of Anuradhapura in 993. It comprises, besides the Brahmanic monuments built by the Cholas, the monumental ruins of the fabulous garden-city created by Parakramabahu I in the 12th century.

The ruins of the capital built by the parricidal King Kassapa I (477–95) lie on the steep slopes and at the summit of a granite peak standing some 370 m high (the 'Lion's Rock', which dominates the jungle from all sides). A series of galleries and staircases emerging from the mouth of a gigantic lion constructed of bricks and plaster provide access to the site.

Founded in the 16th century by the Portuguese, Galle reached the height of its development in the 18th century, before the arrival of the British.

This sacred city was established around a cutting from the 'tree of enlightenment', the Buddha's fig tree, brought there in the 3rd century B.C. by Sanghamitta, the founder of an order of Buddhist nuns. Anuradhapura, a Ceylonese political and religious capital that flourished for 1,300 years, was abandoned after an invasion in 993. Hidden away in dense jungle for many years, the splendid site, with its palaces, monasteries and monuments, is now accessible once again.

This sacred Buddhist site, popularly known as the city of Senkadagalapura, was the last capital of the Sinhala kings whose patronage enabled the Dinahala culture to flourish for more than 2,500 years until the occupation of Sri Lanka by the British in 1815.

Located in south-west Sri Lanka, Sinharaja is the country's last viable area of primary tropical rainforest. More than 60% of the trees are endemic and many of them are considered rare.

The Horton Plain Plateau, is a secluded wilderness sanctuary 2130 m high and offers one of Sri Lanka's most unforgettable views. Here the land plunges down a dizzy gorge to the southern foot hills and on clear days, even a glimpse of the sea more than 80 km away. The Horton Plains are the habitat of giant Rhododendron (an evergreen shrub with large clusters of trumpet shaped flowers), tree fern primrose and daffodil orchids and birds such as the Sri Lanka Whistling Thrush and Arrenga, the Shaggy Bear monkey and the blue mormon butterfly and many other endemic and endangered montane species. Traditionally called 'Maha Eliya' the Horton Plains was founded by Sir Robert Hortain, the British Governor in 1831-37. and established as a nature reserve in 1969 and a National Park in 1988.

Knuckles Mountain Range is important due to the historical value it carries and therefore it can be categorized as one of the valuable heritages in Sri Lanka. The story of Knuckles (Dumbara Hill) goes back into prehistoric periods. It is said that in ancient times it was referred to as 'Giri Divaina' and as 'Malaya Rata' and there is archaeological evidence that speaks of ancient Yaksha settlement in the area. People believe that the name 'Lanka' is derived which much folklore has gathered over the centuries. The Knuckles Mountain Range is an invariable referent in any salutary appreciation of the last kingdom of the Sinhala Kanda Udarata. The importance of the Knuckles Mountain Range is obtained from several factors. It has a parasitical quality to it because of the mountain peaks, the crystal clear and perennial waterways, cloud forests and exquisite fauna and flora. Pregnant with history running into several millennia and a veritable treasure house of cultural heritage, the Knuckles Mountain Range can be considered a as a mirror to the past.
