Anuradhapura
Anuradhapura is a very old city in Sri Lanka. It has giant dome-shaped buildings made of bricks. People built it more than 2,000 years ago.
Anuradhapura, in north-central Sri Lanka, was the island's capital for more than 1,000 years. Its ruins include huge bell-shaped brick monuments called dagobas, monasteries, palaces and ancient reservoirs. It is an important place for Buddhists, and a World Heritage Site since 1982.
Founded in the 5th century BCE, Anuradhapura was the Sinhalese capital from the 4th century BCE until invasions forced the capital's move in the 11th century CE. Its brick stupas, among them the Jetavanaramaya and the Ruwanwelisaya, its monasteries and reservoirs form a UNESCO World Heritage Site (1982).

Discover Anuradhapura
Anuradhapura is in Sri Lanka, an island country in Asia.
Long ago, it was the island's most important city. It has giant round brick buildings shaped like bells, old stone pillars and big ponds for water. Many trees grow among the ruins.
Anuradhapura lies on the plains of north-central Sri Lanka, beside the Aruvi Aru River. For more than 1,000 years it was the capital of the island's kings.
Today its old part is an archaeological park, an area where ruins are protected. Britannica calls it the best known of Sri Lanka's ancient ruined cities. Visitors find enormous bell-shaped monuments called dagobas, or stupas, made of small bricks, along with temples, carvings, palaces and old reservoirs for drinking water. It is an important place of pilgrimage for Buddhists.
Britannica describes Anuradhapura as a city in north-central Sri Lanka on the Aruvi Aru River whose old section, preserved as an archaeological park, is the best known of the country's ancient ruined cities. Around it stand huge bell-shaped dagobas (Buddhist commemorative shrines, or stupas) of small bricks, with temples, sculptures, palaces and ancient drinking-water reservoirs.
UNESCO inscribed the Sacred City of Anuradhapura in 1982, describing a Ceylonese political and religious capital that flourished for 1,300 years before it was abandoned after an invasion in 993, and whose palaces, monasteries and monuments, long hidden by dense jungle, are now accessible again. A CNN report (2026) calls it the island's first great capital.

A capital for 1,300 years
People started the city more than 2,000 years ago.
Kings ruled the island from here for a very long time. Later, the city was left empty, and the jungle grew over it. Much later, people found the ruins again.
Anuradhapura was founded about 2,500 years ago. From the 300s BCE it was the capital of the Sinhalese kings, and UNESCO says it flourished for 1,300 years.
Around 245 BCE, a branch of a famous tree from India was planted here. After an invasion in 993, the city was abandoned, and the capital moved elsewhere. The jungle covered the ruins. In the 1800s, the British rediscovered them, and the city became a center of Buddhist pilgrimage again. Rebuilding the city began in earnest in the 1870s.
Britannica dates the city's founding to the 5th century BCE; it was the Sinhalese capital from the 4th century BCE until the 11th century CE, when invasions from South India forced the capital to move. UNESCO dates the abandonment to an invasion in 993. The city was overrun by jungle, rediscovered by the British in the 19th century, and became a Buddhist pilgrimage center; its revival began in earnest in the 1870s.
UNESCO records that the city grew around a cutting of the Buddha's fig tree brought in the 3rd century BCE by Sanghamitta, founder of an order of Buddhist nuns; Britannica dates the planting to about 245 BCE. CNN's 2026 report describes the great Jetavanaramaya as completed around 301 CE and controversial from the start, built on land associated with the Maha Vihara monastery and later linked to the Sagalika sect.
Mountains of brick
The giant round buildings are made of millions of small bricks.
Workers made the bricks from mud. Elephants may have helped carry them. The builders dug very deep, strong bases first.
The great dagobas are solid domes made of bricks. The biggest, the Jetavanaramaya, used about 93 million bricks! It was finished around the year 301 and was about 122 meters tall, with a spire on top.
The builders were careful engineers. Ancient chronicles say they flooded the dug ground to test how it soaked up water before building. The Jetavanaramaya stands on bedrock and stone foundations 8.5 meters deep. The bricks were held together with mortar made of crushed stone, sand and clay, and covered in lime plaster.
Britannica describes the dagobas as built of small sun-dried bricks; CNN's 2026 report speaks of baked mud bricks, an estimated 93.3 million for the Jetavanaramaya. Guinness World Records lists it as the largest ancient stupa: a base area of 233,000 square meters and 70.4 m high today, about 122 m when completed in 301 with its original spire, on bedrock and stone foundations 8.5 m deep.
CNN reports that the original mortar mixed finely crushed dolomite, limestone, sieved sand and clay; that ancient chronicles describe builders flooding excavated ground to test its absorption; and that archaeologists have found ancient brick kilns around Anuradhapura, though none yet securely linked to the stupa. Historians think elephants and bullock carts were almost certainly used, as at other great sites; Guinness World Records says elephants with leather bindings on their feet pressed down its foundations.
Dagobas, an ancient tree and stone carvings
The biggest dome is called the Jetavanaramaya. Another, the Ruwanwelisaya, is gleaming white.
There is also a very old tree that was planted more than 2,200 years ago. Stone steps and carved stones lead into old buildings.
The Jetavanaramaya was once one of the tallest buildings in the world; today, after parts fell down, it is about 70 meters tall. The gleaming white Ruwanwelisaya, built about 140 BCE, has been looked after ever since and is still a busy place of pilgrimage.
In the city grows an ancient fig tree. It is believed to have grown from a branch of a famous fig tree at Bodh Gaya, in India. It was planted about 245 BCE, and Britannica says it may be the oldest tree in the world with a historical record. All around are ruined monasteries with stone pillars, stairs and carved stones.
Guinness ranks the Jetavanaramaya, at its completion, as one of the tallest buildings in the world, beaten only by two Egyptian pyramids; CNN reports it was the third-largest human-made building of its time and is still the largest brick structure by volume. The Ruwanwelisaya, which CNN dates to 140 BCE, has been continuously maintained and remains the focus of pilgrimage in the city (CNN).
Britannica notes an ancient pipal tree believed to have grown from a branch of the Bo tree at Bodh Gaya, India, planted about 245 BCE and possibly the oldest tree with a historical record. The photograph shows a ruined building of the kind found across the site: stone pillars, a staircase with carved balustrades and a half-moon step, a moss-covered brick platform and a carved stone slab with a standing figure.

Anuradhapura today
Today, many people visit the old city.
Buddhists come to visit and pray. Experts work hard to protect the old bricks and stones.
Today a modern city of about 50,000 people stands beside the ruins. In the middle of the 1900s, much of the town was moved so the ancient capital could be protected. Anuradhapura is also home to the headquarters of Sri Lanka's archaeological survey.
Caring for brick monuments is tricky. Some repairs in the past used cement, and archaeologists now think this may have harmed the old bricks. Pilgrims and visitors keep coming, and more visitors from other countries have arrived in recent years.
Britannica notes that much of the contemporary city was moved during the mid-20th century to preserve the ancient capital; the city (50,595 people in 2012) is a major road junction, lies on a railway line, hosts the headquarters of Sri Lanka's archaeological survey and depends significantly on tourism.
CNN's 2026 report describes the conservation challenge at the Jetavanaramaya: earthquakes, monsoon rains and centuries of abandonment caused collapses; the last major renovation came under Parakramabahu I in the 12th century; and recent restoration that added cement to outer layers may, archaeologists now believe, have accelerated deterioration. Excavations found reliquary caskets and gold panels with Sanskrit texts, now in the National Museum in Colombo.

- Watch Geography What is a World Heritage Site? World Heritage Sites are places so important that they belong, in a way, to everyone. Under a 1972 agreement, countries nominate their most outstanding places, experts check them, and a UNESCO committee decides. By 2026 the list held 1,273 sites: cultural places like the Taj Mahal, natural places like the Galápagos, and mixed ones like Machu Picchu.
- Watch Try it What If? Lab What if buildings had different foundations? A building's whole weight presses down through its foundation onto the ground. A wide foundation spreads that weight out, like snowshoes on snow. In our model, a 200-tonne building on sand is safe on a 40-square-meter footing. Shrink the footing to 8 square meters and it presses five times harder, more than the sand can take, so the building would sink and could crack or tilt.
