Ateshgah, also known as the Fire Temple of Baku, is a religious and cultural monument located in Surakhani, a suburb of Baku, Azerbaijan. The temple is associated with Zoroastrianism, a pre-Islamic religion that was once widely practiced in Azerbaijan and Iran.

The Ateshgah complex is believed to have been built during the 17th and 18th centuries, although there are indications that it may have been used for religious purposes even earlier. The temple is constructed of local limestone and features a central courtyard surrounded by a number of rooms and alcoves. The most distinctive feature of the Ateshgah is its four octagonal towers, each of which is topped by a dome. These towers served as a means of directing the flow of natural gas from beneath the earth's surface into the temple.

The temple is dedicated to the worship of fire, which was considered a sacred element in Zoroastrianism. It is said that pilgrims came from as far away as India and Persia to pay homage to the temple and to worship at its holy flames. The Ateshgah also served as a meeting place for traders and travelers, who would rest and exchange goods and ideas at the temple.

After the decline of Zoroastrianism, the Ateshgah fell into disrepair and was eventually abandoned. In the early 20th century, the temple was restored and converted into a museum, showcasing the history and culture of Azerbaijan. Today, the Ateshgah of Baku is a popular tourist attraction and a symbol of Azerbaijan's rich cultural heritage.
