There is a place on Earth where the flame is "eternal". High flames spread over 10 meters on the hill, making hot days even more scorching.
This is "Yanar Dag", which means "burnt mountain", and it is located on the Absheron Peninsula of Azerbaijan, where Rahila works as a tourist guide.
"This fire has been burning for 4000 years and has not been extinguished. Regardless of rain, snow, wind, the fire never stops burning." Aliyeva Rahila says.
A side effect of the country's abundant natural gas reserves, which sometimes flow to the surface, Yanar Dag is one of several spontaneously occurring fires that have fascinated and frightened travelers to Azerbaijan for millennia.
Venetian explorer Marco Polo wrote of the mysterious phenomena when he passed through the country in the 13th century. Other Silk Road merchants brought news of the flames while traveling to other countries.
Such fires used to be numerous in Azerbaijan, but because they led to a decrease in gas pressure underground, interfering with commercial gas extraction, most have been extinguished.
"Yanar Dag" is one of the few remaining examples and perhaps the most impressive.
At one time they played a key role in the ancient Zoroastrian religion, which was founded in Iran and flourished in Azerbaijan in the first millennium BC, writes CNN.
For Zoroastrians, fire is a link between humans and the supernatural world and a medium through which spiritual insight and wisdom can be gained. It is cleansing, enduring, and a vital part of worship.
Today, most visitors who arrive at the Yanar Dag Visitor Center come for the spectacle rather than religious fulfillment.
