Eagle-eyed as ever, Maik! I've read a bit of the history of Ioannina but that obviously passed me by - tsk tsk! Siver is
big in Ioannina. Plenty of reasonably priced shops and upwards. There's a big silver complex on the shore of Lake Pamvotis close to where I stayed and which I ignored on the two occasions I've been, suspecting the museum was a ploy to get you in to buy the pricey stuff. I may be wrong though...
