Guys, if you're into photography, check
this out. Amazing photos of landscape, animals, different ethnic grps, architecture, etc.. from different parts of Iran. 68 photos in total.
The dome shape architecture, carvings, patterns and stained glass in the photos are pre-Islamic influences, dating back mostly to the Sassanid era.
After viewing the link of photos had to come back and comment further. Thinking the word Amazing perhaps doesn't do some of these photos justice, though cannot think of a better word to describe such. Thanks, odds.
