You really haven't visited Morocco if you haven't sat through at least one "How We Make Our Amazing Rugs (And We Won't Let You Leave Until You Buy One)" presentation. I actually went to Morocco with the intention of buying a rug, so when Hassan asked if we were interested in visiting a rug co-op "to see how rugs are made" (rather than the actual purpose, which was "to buy a rug so I can get a commission"), we said "Sure!"
We went to what must have once been a very, very fine home in the Fes medina. Based on other pictures I've found on the internet, I think we visited the shop with the lovely French name of "Aux Merveilles du Tapis" (or "Wonders of the Carpet" in English). The inner courtyard has become a rug display area, and the high balconies of the second and third floors are perfect for hanging large carpets.
This building was originally owned by a Jewish family. I have in my notes that it was built in 1325 AD, but a date carved on the wall says 1359. Either way, it's ancient by American standards. Judging by the wall decor and the level of maintenance, those who have lived here for the last 800 years have been very wealthy.
