Denmark's only rock island
Well, last week I was on vacation on Bornholm. I always take pictures of nice areas, and try to get some without people on them too. I figured the ones of the Hammershus ruin and surrounding area might serve as inspiration for some nice maps. Maybe some of them can be used for textures as well, I got some granite pics, at least.
Here's a Flickr set of the relevant pictures.
