The Selexyz Dominicanen book store is located in a former Dominican church in Maastricht that's more than 700 years old. Finally, a good use for such a beautiful piece of architecture! I've had the website bookmarked for a while now but haven't been to Maastricht since I found out about it. Every time I see the bookmark I wonder what Polish website I have bookmarked and why. Then I click on it and remember it's a book store that I want to visit. According to the website it is, "the most beautiful bookshop in the world." I haven't been in every book store in the world so I can't confirm this claim :)
