It’s still cold in Berlin, although the snow showers seem to have stopped for now. That doesn’t mean it’s not time for a bracing swim in the river. Design blog Inhabitant writes about the Winter Badeschiff recreation area, created from a sunken cargo ship off the banks of the river in East Berlin, and designed by Berliner artist Suzanne Lorenz. A swimming pool is constructed at near-river level, so you appear to be swimming in the river itself. In the summer it is uncovered, but now delicate white tents cover it, glowing like ice in the evening. It’s open until midnight, with a sandy-floored bar next door.
