World Heritage Sites in Sri Lanka

Ancient City of Polonnaruwa

The Ancient City of Polonnaruwa stands as a powerful reminder of Sri Lanka’s past, serving as the medieval capital which flourished between the 11th and 13th centuries.

The Royal Palace complex is a centrepiece, remarkable for its massive walls and intricate carvings. Nearby, the Sacred Quadrangle holds some of the most revered Buddhist structures, including the Vatadage, which is a circular relic house featuring exquisite stone carvings.

One of the biggest highlights is the colossal Buddha statues at Gal Vihara, carved from solid granite with serene expressions.

Visiting Polonnaruwa is definitely best done by bike, which lets you explore the expansive grounds at a relaxed pace. Make sure to check out the site’s museum, which displays artefacts and gives some important context on the city’s historical significance.

Ancient City of Sigiriya

Sigiriya is one of the symbols of Sri Lanka and one of the country’s most popular tourist attractions. You’ll see why when you get here and start climbing up it yourself!

This 5th-century fortress was built atop a massive 200-metre granite rock by a king who’d stolen the crown from his father (by murdering him) and was terrified of revenge from his brother.

Aside from the exciting history, the site’s significance lies in its innovative urban planning, sophisticated water management, and stunning frescoes. It has elaborate gardens, including water gardens with fountains that amazingly still function today.

When you visit Sigiriya, there’s a challenging but rewarding climb, through the gardens and past ancient ruins before you reach the base of the rock. A series of steep staircases, including the renowned Lion’s Paw entrance, lead to the summit.

Along the way, you can see the Mirror Wall, which was once polished so finely that it reflected the frescoes above. The panoramic views from the top are breathtaking, encompassing lush forests and distant mountains.

But, as the busiest World Heritage Sites in Sri Lanka, be prepared for tourist crowds during peak seasons.

Sacred City of Anuradhapura

The Sacred City of Anuradhapura, found in Sri Lanka’s North Central Province, served as the country’s capital from its founding in the 4th century BC until the 11th century.

It’s a huge World Heritage Site with immense historical and religious significance, not just because of its well-preserved ruins, but for the sheer scale of the architecture and engineering.

The city is a complex network of monasteries, palaces, and monumental dagobas (Buddhist stupas). Along with the manmade structures, there’s also the sacred Sri Maha Bodhi tree, believed to be the oldest documented tree on Earth!

When you visit Anuradhapura, much of it will feel like a large archaeological park. But for locals and pilgrims, it’s still a hugely important spiritual location, so you’ll often see worshippers offering flowers and prayers at various shrines.

I would recommend setting aside a full day here and renting a bicycle or taking a tuk-tuk, as the site is huge and you’ll want to see everything properly.

Old Town of Galle and its Fortifications

The Old Town of Galle, on Sri Lanka’s southwestern coast, is a really popular spot for tourists and has a wonderful fusion of European and South Asian architectural styles that you can explore.

The fortified city was founded by Portuguese colonists in the 16th century and later developed by the Dutch and British. You can see their influence in the Dutch colonial buildings, churches, mosques, and grand mansions.

The old town’s most striking feature is its imposing sea wall and bastions, which have held up over time and even protected the town from the devastating 2004 tsunami.

For some of best things to see in Galle, climb the ramparts for panoramic views of the Indian Ocean, then wander through the narrow streets to browse the restored buildings.

In particular, look out for the Dutch Reformed Church, the Galle Lighthouse, and the National Maritime Museum.

Many people come as a day trip but I would recommend spending the night so you can see it without the tourists and stay in one of the lovely boutique hotels.

Sacred City of Kandy

The Sacred City of Kandy, nestled in the central highlands, was the last capital of the Sinhala kings. Now, with a history spanning over 2,500 years, its sites embody the pinnacle of traditional Buddhist spirituality in Sri Lanka.

At the heart of the city is the Temple of the Sacred Tooth Relic, which houses one of Buddhism’s most revered relics: a tooth of the Buddha.

The magnificent temple complex itself is worth seeing for its intricate architecture, but I think one of the most interesting things is being amongst the crowds of worshippers.

Kandy is visually striking, surrounded by lush hills and centred around the famous Kandy Lake. Its aesthetic is unique, blending colonial architecture with traditional Kandyan designs.

Strolling through the streets, you’ll find vibrant markets and the extensive Royal Botanical Gardens. For culture, the city offers traditional dance performances and ancient crafts, which give fascinating insights into Sri Lanka’s royal heritage.

Sinharaja Forest Reserve

The Sinharaja Forest Reserve is Sri Lanka’s last viable area of primary tropical rainforest and a hugely important World Heritage Site. It’s home to over half of Sri Lanka’s endemic species of mammals and butterflies, as well as many birds, insects, reptiles, and amphibians.

Spanning about 11,000 hectares, this biodiversity hotspot is renowned for its incredible collection of native plants, with more than half the country’s endemic trees and woody climbers.

Look up when you’re here, and you may have trouble seeing the forest’s canopy, which reaches heights of up to 45 metres, creating a lush, multi-layered ecosystem teeming with life.

Guided walks are the only way to explore, giving you the best chance to spot elusive wildlife such as the purple-faced langur. Trekking through the dense undergrowth, the sounds are constant, from the calls of birds like the Sri Lanka blue magpie to the rustling leaves.

Golden Temple of Dambulla

The Golden Temple of Dambulla is a remarkable cave temple complex in central Sri Lanka that has incredibly well-preserved Buddhist mural paintings and sculptures, dating back as early as the 1st century BC.

The site is made up of five caves, each covered with intricate artwork depicting Buddha’s life and Sri Lankan history. The largest, the Cave of the Great Kings, houses over 50 Buddha statues.

The walls and ceilings of the caves are a riot of colour, with centuries-old paintings still impressively vibrant. Even in the dim spaces of cool air, there’s so much brightness!

Visiting the Dambulla Cave Temple is easy, but there’s a bit of a climb up to the main part of the site from the enormous golden Buddha statue atop the modern temple building.

But don’t let the walk put you off. It’s worth heading up to the ancient caves to see this spiritual art gallery of golden statues and paintings on the rock faces.

Central Highlands of Sri Lanka

The Central Highlands of Sri Lanka is a vast area covering lush mountainous terrain in the centre of the country.

The site’s value comes from its remarkable biodiversity and unique ecosystems, home to many endemic species. The montane forests here are vital, acting as the watershed for the country’s major rivers.

There are lots of things for visitors to do here, but it’s particularly popular for trekkers looking to explore mist-shrouded trails through pristine forests.

The World Heritage Site is made up of three distinct protected areas: the Peak Wilderness Protected Area, the Horton Plains National Park, and the Knuckles Conservation Forest.

One of the easiest and most popular parts to access is Horton Plains, which features the dramatic World’s End, a sheer cliff with views stretching a long way on a clear day.

But if you’re up for a challenge, you can climb Adam’s Peak in the Peak Wilderness Area, a sacred mountain that attracts pilgrims with its path illuminated during the pilgrimage season.
