The Meistersaal am Potsdamer Platz is a famous concert hall in Berlin, known for its use as Studio 2 of the Hansa recording studios. David Bowie called it "the big hall by the wall" and recorded albums here. Iggy Pop also recorded in the Meistersaal am Potsdamer Platz, as did U2 in 1990. The Meistersaal am Potsdamer Platz got its name because journeymen received their master's certificates here.
