Borobudur, or Barabudur, is a 9th-century Mahayana Buddhist monument near Magelang, Central Java, Indonesia.
The monument comprises six square platforms topped by three circular platforms, and is decorated with 2,672 relief panels and 504 Buddha statues.
A main dome, located at the center of the top platform, is surrounded by 72 Buddha statues seated inside perforated stupa.
The monument is both a shrine to the Lord Buddha and a place for Buddhist pilgrimage.

Evidence suggests Borobudur was abandoned following the 14th-century decline of Buddhist and Hindu kingdoms in Java, and the Javanese conversion to Islam.Worldwide knowledge of its existence was sparked in 1814 by Sir Thomas Stamford Raffles, then the British ruler of Java, who was advised of its location by native Indonesians.
Borobudur has since been preserved through several restorations. The largest restoration project was undertaken between 1975 and 1982 by the Indonesian government and UNESCO, following which the monument was listed as a UNESCO World Heritage Site.  Borobudur is still used for pilgrimage; once a year Buddhists in Indonesia celebrate Vesak at the monument, and Borobudur is Indonesia's single most visited tourist attraction.
