A cousin in Hamburg just posted a bunch of photos from a Middle Ages Fair in Germany. Apparently it happens one weekend, first weekend in September, annually.
It looked both interesting and entertaining. The pictures showed lots of people in costume - mostly middle age armor or Viking outfits, some fantasy costumes (e.g. orcs). There was a stage for what appeared to be traditional music and a lot of long tables like a beer garden.
I went to April Fair in Seville. It was a great cultural experience and like stepping back in time (but not more than a century or two). Holy Thursday in Zaragosa was another great event that I'd recommend to anyone. The April Fair didn't feel touristy though I'm sure there were many in attendance. We seemed to be the token tourists in Zaragosa.
I went to the iconic Oktoberfest in Munich but really enjoyed the Bonnfest (which was earlier in September) as a similar but more local, vs. tourist, event.
Anyone have any favorite fairs they've visited in Europe.
