Borobudur Hindu-Buddhist Temple in Indonesia

The first five terraces are square and surrounded by walls adorned with Buddhist sculpture in bas-relief; the upper three are circular, each with a circle of bell-shaped stupas (Buddhist shrines). The entire edifice is crowned by a large stupa at the center of the top circle. The way to the summit extends through some 4.8 km (some 3 mi) of passages and stairways. The design of Borobudur, a temple-mountain symbolizing the structure of the universe, influenced temples built at Angkor, Cambodia. Borobudur was rededicated as an Indonesian national monument in 1983 following extensive reclamation, aided by the United Nations.

Borobudur lay hidden for centuries under layers of volcanic ash and jungle growth. The facts behind its abandonment remain a mystery. It is not known when active use of the monument and Buddhist pilgrimage to it ceased. Somewhere between 928 and 1006, the center of power moved to East Java region and a series of volcanic eruptions took place; it is not certain whether the latter influenced the former but several sources mention this as the most likely period of abandonment. Soekmono (1976) also mentions the popular belief that the temples were disbanded when the population converted to Islam in the fifteenth century.

Borobudur attracted attention in 1885, when Yzerman, the Chairman of the Archaeological Society in Yogyakarta, made a discovery about the hidden foot. Photographs that reveal reliefs on the hidden foot were made in 1890–1891. The discovery led the Dutch East Indies government to take steps to safeguard the monument. In 1900, the government set up a commission consisting of three officials to assess the monument: Brandes, an art historian, Theodoor van Erp, a Dutch army engineer officer, and Van de Kamer, a construction engineer from the Department of Public Works.

Borobudur is built as a single large stupa, and when viewed from above takes the form of a giant tantric Buddhist mandala, simultaneously representing the Buddhist cosmology and the nature of mind. The foundation is a square, approximately 118 meters (387 ft) on each side. It has nine platforms, of which the lower six are square and the upper three are circular. The upper platform features seventy-two small stupas surrounding one large central stupa. Each stupa is bell-shaped and pierced by numerous decorative openings. Statues of the Buddha sit inside the pierced enclosures.

Borobudur contains approximately 2,670 individual bas reliefs (1,460 narrative and 1,212 decorative panels), which cover the façades and balustrades. The total relief surface is 2,500 square meters (26,909.8 sq ft) and they are distributed at the hidden foot (Kamadhatu) and the five square platforms (Rupadhatu).
