A team of 100 graffiti artists was asked to paint the walls of a student dormitory at the Cité Internationale Universitaire in Paris as a part of Rehab 2, an urban festival that ran from 16 June to 16 July. Unfortunately, all of the art will be gone soon due to the official renovation of the dormitory.

This old asylum area in Michigan was opened in 1885 but closed permanently in 1989. Some recent reconstruction of the buildings has turned it into a flourishing hotel, office and shopping centre.

Photographer Stefan Koppelkamm took these pictures of East Germany in the early 90s, soon after the German reunification, when much of the buildings had yet to be rebuilt. He returned ten years later to take photos of the same locations, and found them completely transformed for the better.
