European Plucked String Instrument trade Shows.

I'm thinking I'd like to make a trip to Europe next spring/summer to check out some guitar/lute convention/trade shows. And possibly bring along a couple of my instruments to show.

Can anyone recommend a few that might include period instrument makers of guitars, vihuelas, lutes? Any comparable to North Americas GFA? http://www.guitarfoundation.org/drupal/

And any smaller regional ones that cater to the instruments noted above and their makers.
