House of the Hellenic Broadcasting Corporation, Broadcasting headquarters in Agia Paraskevi, Greece.

The House of the Hellenic Broadcasting Corporation is a four-story building containing numerous studios for radio and television production along Mesogeion Avenue. The structure houses production facilities, archives, and departments that support different areas of the public broadcasting service.

The building began operations in 1969 and formally opened in January 1974 as the main center for Greek public broadcasting services. It underwent multiple institutional changes between 2013 and 2015, housing different broadcasting entities before returning to Hellenic Broadcasting Corporation management.

The forecourt of the Radiomegaro is used as a venue for events, and the building's central gate carried a clock that was deactivated on 13 April 2014, when the Greek sign "ELLINIKI RADIOFONIA TILEORASI" and the other ERT markings were taken down. The sign returned to the roof on 4 November 2017.

The building stands on Mesogeion Avenue in Agia Paraskevi, reachable by bus or metro from central Athens. It is a working state broadcaster, so access is limited to the exterior and the forecourt, which is used for events. Check in advance whether any guided visit is possible.

The rooftop sign has its own history: the original blue-background "ELLINIKI RADIOFONIA TILEORASI" lettering was taken down on 13 April 2014, replaced by an all-blue NERIT sign on 20 September 2014, cut to "ERT" on 8 June 2015, and the full Greek name was put back on the roof on 4 November 2017.
