Kashan
Region:
Iran Kashan has some things well worth visiting that I hadn't come across elsewhere. Unfortunately the accomodation available is both overpriced and unappealing, so I recommend a hit and run technique, taking in as much as you can and getting back out again.
The restored old houses mentioned in the lonely planet are very much worth the effort of seeing. Like most "museums", prices have dropped so that foreigners pay the same prices as locals. Restoration seems to have come to a halt; when we visited in 2007, it was underway everywhere we went, but there doesn't seem to be much happening right now and little progress has been made since then.
