One of the branches of a popular Dutch online bookstore Selexyz is located right in the Dominican church of the 13th century in Maastricht (The Netherlands).
The project, known as Selexyz Dominicanen Maastricht, developed by the architectural studio of Merkx + Girod. This is a brilliant union of opposing aesthetics. The Cathedral was built in 1294. In the room there is even a bookstore cafe (on the former site of the cathedral choir).
