It is a scene of desolation, of nodding donkeys as far as the eye can see, not helped by the grey sky from which came steady rain that turned the soil to a heavy mix of oil and mud. To the south of Baku is a similar field that is called the James Bond Oil Field as that's where they filmed one of the series.
But the natural resource made Baku money even further back in history. Along with oil there is also gas, and this gas in places finds its way to the surface where it can catch fire.
And one such place can be found at the so called "Fire Mountain" or Yanar Dag (below) where a ribbon of rock burns continuously.
But fire has caught the imagination of us humans since the dawn of time and was a central part of both Zoroastrianism and Hinduism. And so its natural that these ever lasting fires have been a magnet for these religions.
Just north of Baku is the Atesgah Fire Temple within which once burnt one of these fires, and which was a magnet for pilgrims from as far away as India.
