Borobudur is a 9th century Mahayana Buddhist temple located in Indonesia. It consists of nine stacked platforms topped by a central dome, decorated with over 500 Buddha statues and 2,672 relief panels. The temple was hidden for centuries before being rediscovered in 1814. It was built in the 8th-9th centuries during the reign of the Shailendra dynasty and took 75 years to complete. Borobudur's layout and symbolism represent Buddhist cosmology. It faced threats from natural disasters and was restored in a major international project in the 1970s.
