We can understand from the passage that ……..

Esfahan has the greatest concentration of Islamic monuments in Iran. The cool blue tiles of Esfahan contrast perfectly with the hot dry Iranian countryside around it. Esfahan is a sight you won't forget. Not only is the architecture superb and the climate pleasant, but there's a fairly relaxed atmosphere here compared with many other Iranian towns. It's a city for walking, getting lost in the bazaar, dozing in the beautiful gardens and meeting people. The more time you have, the better, because here it's easy to appreciate many of the best aspects of Persian culture.
