hr-Sendesaal, formerly Großer Sendesaal des Hessischen Rundfunks (Large broadcasting hall of the Hessischer Rundfunk) is a music hall and former television studio based in Frankfurt am Main, Germany.
Construction of the music hall began when the foundation stone was laid on 28 February 1953, and was ready for use on 30 September 1954.
[2] Although the hall was mainly built for radio, television broadcasts were also produced from there in the early years.
In 1968, a debate was held on the German Notstandsgesetze (Emergency Acts), which were introduced the same year.
Walls and ceilings are equipped with 60,000 sound-absorbing round wooden boards, these were installed to provide the best possible acoustics for radio.
