Borobudur
Borobudur is a giant stone temple on the island of Java, in Indonesia. It looks like a big stepped hill. It has lots of bell-shaped towers and carvings.
Borobudur is a huge Buddhist monument in central Java, Indonesia, built about 1,200 years ago. It is shaped like a stepped pyramid around a small hill, with carved walls and 72 bell-shaped stupas on its round top terraces. For centuries it lay hidden under volcanic ash and plants, and today it is a UNESCO World Heritage Site.
Built between about 778 and 850 CE under the Shailendra dynasty, Borobudur wraps 56,600 m³ of volcanic stone around a natural hill: a square base, five square terraces and three circular ones, crowned by a stupa 35 m above the base. Buried under ash from about 1000 and restored in 1907 to 1911 and 1973 to 1983, it was inscribed by UNESCO in 1991.

Discover Borobudur
Borobudur is on Java, an island in Indonesia.
It is a giant temple made of gray stone. It is built like a big cake with layers, getting smaller toward the top. Bell-shaped towers sit on the round top layers.
Borobudur stands in the Kedu Valley in central Java, about 42 kilometers northwest of the city of Yogyakarta. It is a Buddhist monument, built between about 778 and 850 CE, when a family of kings called the Shailendra dynasty ruled the area.
The monument is built around a small natural hill, like a giant stepped pyramid. Its walls are covered in carved pictures, and on its round upper terraces stand 72 stone stupas shaped like bells, most of them still holding a statue of the Buddha. UNESCO made Borobudur a World Heritage Site in 1991, together with two smaller temples nearby, Mendut and Pawon.
Borobudur lies in the Kedu Valley of southern Central Java, 42 km northwest of Yogyakarta. UNESCO calls it one of the greatest Buddhist monuments in the world and an outstanding dynastic monument of the Shailendra dynasty, under which Britannica dates its construction to about 778 to 850 CE.
The World Heritage property (1991) comprises three monuments on a straight east-west axis: Borobudur itself and the smaller Mendut and Pawon temples to the east. UNESCO notes that Borobudur's art and architecture, from the early 8th to late 9th centuries, influenced an architectural revival in Indonesia between the mid-13th and early 16th centuries. Britannica traces its style to Indian Gupta and post-Gupta art.

Built, buried and found again
People built Borobudur more than 1,000 years ago.
Later, a volcano covered it with ash, and plants grew all over it. For a long time it was hidden. Then people cleared it and fixed it.
Borobudur was used as a Buddhist temple for a long time after it was built. Then, sometime between the 900s and 1400s, it was abandoned. From about the year 1000, it lay buried under volcanic ash and overgrown with plants.
In 1814, it came to the attention of the English lieutenant governor Thomas Stamford Raffles. Dutch archaeologists restored it from 1907 to 1911. A second, much bigger restoration, with help from UNESCO, took place from 1973 to 1983.
UNESCO records that Borobudur served as a Buddhist temple from its construction until sometime between the 10th and 15th centuries, when it was abandoned. Britannica adds that it was buried under volcanic ash from about 1000 and overgrown until it came to the attention of the English lieutenant governor Thomas Stamford Raffles in 1814; UNESCO describes this as its rediscovery in the 19th century.
Restoration came in two 20th-century phases: by a team of Dutch archaeologists in 1907 to 1911, and in 1973 to 1983 with UNESCO's help. UNESCO judges that, although today's monument is the result of these restorations, enough original material survived to make reconstruction possible, and mostly original stone was used, with some additions to strengthen it and improve drainage.
Stone wrapped around a hill
Builders did not start on flat ground. They built Borobudur around a small hill.
They stacked gray stone from volcanoes, layer upon layer. At the very top is one big bell-shaped tower.
Builders wrapped Borobudur around a small natural hill, using about 56,600 cubic meters of gray volcanic stone. They shaped it into three main parts: a square base, then five square terraces, then three round terraces on top.
At the very center, 35 meters above the base, sits one large stupa. Because the monument has no roof over its terraces, it is like an open, climbable mountain of stone. Walkways run around each level, and stairways lead upward.
Britannica describes about 56,600 m³ (2 million cubic feet) of gray volcanic stone enclosing a small hill, shaped as a stepped pyramid of three major levels: a square base, a middle level of five square terraces and an upper level of three circular terraces, with a large stupa at the center 35 m above the base. UNESCO describes the whole as a stepped, unroofed pyramid of ten superimposed terraces crowned by a large bell-shaped dome.
The walls and balustrades carry fine low reliefs covering 2,520 m², according to UNESCO. Around the circular platforms stand 72 openwork stupas, each containing a statue of the Buddha. UNESCO also notes a growing rate of deterioration of the building stone, whose cause needs more research.
Carvings and bell-shaped stupas
The walls of Borobudur are covered in carved pictures. People look at them as they climb.
On the top layers are 72 stone bells with holes in them. Inside most of them sits a statue.
Borobudur's walls and railings are covered with carved stone pictures called reliefs, about 2,520 square meters of them, about the area of six basketball courts. As people climb, they walk around each level and pass carving after carving.
On the three round terraces stand 72 bell-shaped stupas made of stone lattice, full of holes, so you can peek at the statue of the Buddha sitting inside many of them. People following the traditional route start at the east stairway and walk around every level before reaching the top, more than 5 kilometers in all.
UNESCO's figure of 2,520 m² of low reliefs makes Borobudur's carved surface its defining feature: the walls and balustrades of the square terraces form galleries lined with relief panels. Britannica notes that the hundreds of reliefs at the lowest level are partially hidden.
The three circular terraces carry 72 openwork stupas, perforated bell shapes built to shelter statues of the Buddha (Britannica notes that many still contain one), around the large central stupa. Britannica describes the traditional route: a pilgrim begins at the eastern stairway and walks clockwise around each of the nine levels before reaching the top, a distance of more than 5 km. The photograph shows people in robes walking in procession at the foot of the monument.

Protecting Borobudur
Today, many visitors come to see Borobudur.
People work hard to protect it from volcano ash and too many feet.
Borobudur is protected by Indonesian law and by UNESCO. Its keepers have to deal with many challenges. Mount Merapi, a volcano nearby, covered the temple with acidic ash in 2010. Huge numbers of tourists put pressure on the site, and some visitors have damaged the stone.
UNESCO also warns that new buildings around the temple could spoil its setting, and that the stone is slowly wearing away. UNESCO says more research is needed to find out why.
Borobudur is protected under Indonesia's Law No. 11/2010 on Cultural Heritage and managed within a National Strategic Area. UNESCO lists the main threats: development that could compromise the relationship between the monument and its wider setting, heavy tourism pressure, a small degree of damage by unsupervised visitors, uncontrolled commercial activity and a growing rate of stone deterioration whose cause needs further research.
The eruption of Mount Merapi is also a potential threat, as in 2010, when it deposited acidic ash on the monument. UNESCO adds that the property can be used today as a Buddhist pilgrimage site, as the procession in the photograph shows.
