Please Help Me Find This Mystery Location!

This will be a difficult question for all but the most well versed European travel experts. I am looking for a destination that I once saw on the cover of a travel magazine. It was a small European town situated on a rock in the middle of lake surrounded by mountains. The town had medieval style walls and it was connected to the land by a single bridge. It looked a bit like Mont St. Michel, but it was much smaller. If anyone has any ideas as to the name of this location, please help me out.

Lindau in Bavaria (Germany) would be a possibility. The old city is situated on an island in Lake Constance and connected to the shore of the lake with a bridge. Mountains would fit too. But it has been a very long time since I was there, I am unsure about the medievial walls.

You could try the Trakai Castle on Lake Galve in Lithuania. It 's about 30km west of Vilnius and gets photographed a lot for magazine stock images.
Hope this is some help.

Did you find what you're looking for? If it was Trakai, I can give a little more travel advice on the place, as I have just come back from there.

It has been a while since I've been to Lindau as well (though I thought it was in Baden-Wurtemberg . . .?), but, still, I don't remember any medieval walls surrounding it, either. It is located on Lake Constance (Bodensee) on a small island accessable by train. You can see the Austrian Alps in the distance. Hmmm . . .

Perhaps one of the travel helpers will know? . . .
