The Baku Ateshgah (from Persian: آتشگاه Atashgāh, Azerbaijani: Atəşgah ) or "Fire Temple" is an ancient Hindu castle-like religious temple dedicated to Jwala Ji in Surakhani, a suburb of greater Baku, Azerbaijan, which was initially recognized as a Zoroastrian fire worship place. "Atash" (آتش) is the Persian word for fire. The pentagonal complex, which has a courtyard surrounded by cells for monks and a tetrapillar-altar in the middle, was built during the 17th and 18th centuries.
