The Umlauftank 2 (UT2, 1967-1974) is one of Berlin’s more enigmatic landmarks. Its architect, Ludwig Leo, was still alive when it was designated for historic preservation.

The iconic construction is a place for experiment - a laboratory for fluid dynamics, for architecture, and, now since it has been refurbished, for the upkeep of young landmarks. In this book, a wealth of illustrations and a lively mix of literary and historical, technical and analytical texts illuminate the many aspects of a creative process that is today deemed utopian.
