Molecule Man

American artist Jonathan Borofsky's Molecule Man was installed in 1999 at the spot where the districts of Treptow, Kreuzberg, and Friedrichshain converge on the river, its three perforated aluminum figures symbolizing molecules connecting people across the formerly divided city. It's best appreciated from a boat on the Spree or from the riverbank near Ostkreuz, where the piece catches dramatically different light at different times of day, as reviewers note. Free and unmissable once you know to look for it, it's less a planned destination than a striking landmark to notice while exploring the river or heading to nearby Treptower Park. A quick fifteen-minute stop suffices unless you're taking photos from multiple angles.
