The Sendesaal Bremen, previously named Radio Bremen Sendesaal (Studio F), is a recording and live performance venue with seating for up to 250 people, located in the Schwachhausen district of Bremen (Germany). It was previously used by the broadcaster Radio Bremen between 1952 und 2007.
A virtually revolutionary construction method was tested and successfully introduced here: the hall is built completely room-in-room, ceilings and walls of the interior are supported on 655 springs of the outer shell, whereby the interior is optimally insulated against external noise. For 55 years it served Radio Bremen as its best music studio. Historically important recordings and concerts were held there by John Cage, Alfred Brendel, Keith Jarrett and Nikolaus Harnoncourt, to name a few.
Radio Bremen moved to a new building in 2007, giving up the old premises, including the broadcasting hall. In March 2009, the citizens' initiative "Friends of the Broadcasting Hall Association" took over the venue, renamed the Alter Sendesaal, Bremen, which, in addition to the broadcasting hall, includes a small spoken word studio and a state-of-the-art radio play studio.
