The most striking feature of this Zoroastrian sanctuary is the crater lake around which it was built. It is too deep to be fathomed and too wide to fit in Phespirit's photograph.
For Phespirit, the top unmissable attraction in Iran was ancient Persepolis.
Like Phespirit's own past, it's behind him.
Zoroastrians practiced 'sky burial', the ritual of leaving their dead exposed upon a 'Tower of Silence' for the vultures to pick clean.
Here is one such tower in Yazd.
