This is the staircase to a shop and art gallery, in the Mitte district of Berlin.
On the first floor you’ll find the Neurotitan shop & Gallery (you can visit the gallery for 2 euro), on the second floor is the Stockx clothing shop. For a long time the building was a crack house until in the nineties a few artists decided to make use of the empty spaces. It’s actually hip now to have a store out here. Would you go up if there was no one around?
