I went to Iran expecting to be bowled over by the blue mosaics - I certainly enjoyed them but what got to me unexpectedly was the Zoroastrian sites ( more about Yazd in another post).
We felt really privileged to see Takht-I Soleiman in the snow - it wouldn't have had half the impact in the heat of summer. The combination of the sparkle from the snow and the reflections of the ruins in the steam rising from the sacred lake ( warm at about 37 c) made it spectacularly atmospheric. You could see how the ancients would have selected and venerated such a site.

Location of fire temple - Zoroastrians do not venerate fire as such but what it represents; goodness and purifying energy
