Muara Jambi Temple is considered one of the richest archaeological sites on the island of Sumatra. The eight temple-like structures appear to be Buddhist, and were probably built around the 14th century.
Archaelogists conclude that the site was the center of Old Jambi, the capital of ancient Malay kingdom which reigned supreme about ten centuries ago. The capital was sieged and destroyed in 1377 by armies from Burma. For centuries, the site had been lost and forgotten deep in the jungle, only to be rediscovered in 1920 by a British military expedition teamhttp://indonesia.travel/en/destination/64/muara-jambi-temple
