The temple is made of gray andesite stone and has nine platforms topped by a central dome.[2] Borobudur has 2,672 relief panels and originally had 504 Buddha statues. The central dome is surrounded by 72 Buddha statues within perforated stupas

Borobudur has a complex system of stairways and corridors with 1,460 relief panels, making it one of the world's largest collections of Buddhist reliefs.

It was built during the Sailendra Dynasty's reign in Java. Borobudur blends Javanese Buddhist architecture with other indigenous Indonesian traditions. The temple was later abandoned in the 14th century when people in started to convert to Islam. Thomas Stamford Raffles rediscovered Borobudur in 1814, leading to its preservation through various restorations, including a major one in 1983 by the Indonesian government and UNESCO.[5] It is now a UNESCO World Heritage Site.

In Indonesian, ancient temples are referred to as candi; thus locals refer to "Borobudur Temple" as Candi Borobudur. The term candi also loosely describes ancient structures, for example, gates and baths. The origins of name Borobudur, is derived from Boro for big and Budur for Buddha.[8] Dutch scholar J. L. Moens says the court poet Mpu Prapanca referred to a holy sanctuary at "Budur" in 1365.[9] Stamford Raffles mentioned "Bóro Bódo" and described the temple in his 1817 book on Javan history.[10][11] In a footnote, Raffles says, "Bóro is the name of the district, and bódo means ancient."[12] Most candi are named after a nearby village. If it followed Javanese language conventions and was named after the nearby village of Bore, the monument should have been named "BudurBoro". Soekmono says Raffles thought that Budur might correspond to the modern Javanese word Buda ("ancient")—i.e., "ancient Boro".[8] He also suggested that the name might derive from boro, meaning "great" or "honorable" and Budur for Buddha.[8] However, another archaeologist suggests the second component of the name (Budur) comes from Javanese term bhudhara ("mountain")

Another possible etymology by Dutch archaeologist A.J. Bernet Kempers suggests that Borobudur is a corrupted simplified local Javanese pronunciation of Biara Beduhur written in Sanskrit as Vihara Buddha Uhr. The term Buddha-Uhr could mean "the city of Buddhas", while another possible term Beduhur is probably an Old Javanese term, still surviving today in Balinese vocabulary, which means "a high place", constructed from the stem word dhuhur or luhur (high). This suggests that Borobudur means vihara of Buddha located on a high place or on a hill.

The construction and inauguration of a sacred Buddhist building—possibly a reference to Borobudur—was mentioned in two inscriptions, both discovered in Kedu, Temanggung Regency. The Karangtengah inscription, dated 824, mentioned a sacred building named Jinalaya (the realm of those who have conquered worldly desire and reached enlightenment), inaugurated by Pramodhawardhani, daughter of Samaratungga. The Tri Tepusan inscription, dated 842, is mentioned in the sima, the (tax-free) lands awarded by Çrī Kahulunnan (Pramodhawardhani) to ensure the funding and maintenance of a Kamūlān called Bhūmisambhāra.[15] Kamūlān is from the word mula, which means "the place of origin", a sacred building to honor the ancestors, probably those of the Sailendras. Johannes Gijsbertus de Casparis suggested that Bhūmi Sambhāra Bhudhāra, Sanskrit for a mountain of combined virtues after the ten stages of Boddhisattvahood, was the original name of Borobudur.
