Just saw this, I had exchanged some cash at the airport because you probably need some to a) get SIM card b) get a ride to the hotel but only exchange very little because these guys try to give you a low rate. Once you are in town there are lots of exchange places and their rate is usually always the same.

Persian caravanserais seems to be in the running for nomination by Iran in the next years:

Iran has no nomination yet for 2023, so this could be it.

Iran seeks UNESCO recognition for millennia-old petroglyphs (Teymareh petroglyphs in Khomein county of Markazi province)

I don't see this on Iran's Tentative List yet.

Iranian newspaper Iran Daily reports that the country is working on multiple nominations at the same time: the Persian Caravanserais and no less than 3 extensions - an additional Hyrcanian forest at Dizmar, another Armenian Orthodox Church (Vank in Isfahan) and Nasqsh-e Rostam and Naqsh-e Rajab in addition to Persepolis.

Just finished adding descriptions to all 57 Iranian TWHS.

Iran seems to know the ropes about getting sites inscribed, but its T List is rather messy:
- There's a triple TWHS entry Qasr-e Shirin (2x on its own and once caravanserai).
- Izadkhast (looks pretty on photos) also part of Caravanserai and possibly also Silk Road (which is without hint of a location at all).
- Ghaznavi- Seljukian Axis in Khorasan also 2 caravanserais
- Tape Sialk is also double (alone and as part of axis of fin,sialk, kashan)
- Lots of uninspirational, short texts (Zozan or "There is not similar area in Iran or in the world." Or try to make sense of this)
- 5 sites have already been inscribed in one way or another, and 3 are proposed extensions.
- Kharghan (of Bastam and Kharghan) probably is nearby Kharghani, but whether that has monuments as well or is this just an indication where Bastam is located?
- Ruchun Wildlife Refuge? – no idea where it is or what it is about

Among the better ones:
- Taq-e Bostan
- Possibly Touran ("little africa) with critically endangered asian cheetah.
- The Caravanserais can be good, but choose a good selection and do not put those sites forward as well as single entries or as part of Silk Road
- The Collection of Historical Bridges is better than it sounds.
- Nasqsh-e Rostam and Naqsh-e Rajab
- Abyaneh (possibly the best among the multiple vernacular villages on the T List of Iran)
