I am currently mapping out a 19th century Persian city and need some websites/books for inspiration, city plans and general research. Was wondering if any of you nice folk know of any sites or books that can assist me with the following:

1. Plans, drawings, elevations, layout etc. for traditional Persian residential architecture, caravanserais (inns), Mosques, bazaars, palaces, forts etc.

2. Detailed information on Persian city planning/formation from ancient times right up to the 19th century

I've already raided Wikipedia for every last drop of information, including most of the links therein to external sites. If you have any pointers, advice, links or know any good books, please let me know!

One day I may even pop some thumbnails, WIPs and, ultimately, some finished works here...
