Located in the Baku suburb Surakhani and dating back to the 17th century, this pentagonal temple complex is thought to have been built by a local Hindu Indian community and was used by Hindus, Sikhs, and Zoroastrians. Its mystique derives from its keeping of ever-burning flames from a natural gas field underneath it (the field was eventually exhausted, and today the gas is piped in from Baku).
