Instead of lengthy words, which will still fail to describe, I will just leave some pictures here (again with annotations).

Imam Square with the Imam Mosque (entrance and dome) on the southern side. Built by the Safavid dynasty at the end of the 16th. century it is the central square of Isfahan.

This craftsman invited me to his workshop to practice his english language skills and show me his work. He was manufacturing specially shaped wires to sell to traditional artisans on the bazaar.

Iranian Food: flatbread, soup, spiced and mashed potatoes, doogh (fermented yoghurt drink) and a raw onion. Other patrons told me how to eat it correctly, the bread has to be ripped to little pieces and soaked in the soup. Delicious.

Sheikh Lotfollah Mosque: an especially beautiful example of the typical muslim decoration consisting of geometric patterns and calligraphy.

Vank cathedral in the Armenian Quarter. A somewhat strange mixture of iranian/muslim architecture on the outside (except for the cross on its roof) and christian sacral art on the inside.

You can find everything on the bazaar (probably even an oil lamp including the djinn). Except for the one item you are actually searching for, a box of dates in my case, something I saw on every second corner the day before, but now I had to search for an hour and ask several people before I found one.

Atashgah, a Zoroastrian fire temple on a rock on the outskirts of the city. The old persian religion still has some followers in Iran.

Then there was this guy who wanted to show me his garden after he saw me taking a picture through the gate.

A shoemaker patches a hole in one of my gloves. Often people refuse to take a payment for small services like this.

One of the many mosques, four iwans (open half-domes) surround a square, where carpets are rolled out for prayers.

Zayandeh river: due to a rather wasteful consumption and bad water management Zayanderud is a rather pitiful trickle.
And because images are the wrong medium to convey songs, here is a video of the singers under the Khaju Bridge:
