The Grade II listed venue, managed by its in-house event and hospitality brand Events & Hospitality QM, played host to the new documentary series produced by Wall to Wall.
The show, which first broadcast on Channel 4 on Tuesday (11 June) at 9pm, will run for four weeks following the lives of some of the country’s cleverest children and their families.
Sue Mussett, business development manager for Events & Hospitality QM, said: "We are pleased with the growing recognition and reputation of our facilities for filming.
"The Octagon has hosted the BBC’s Question Time and Free Speech programmes, alongside Child Genius, while other facilities have featured in Twenty Twelve and most recently ITV’s The Job Lot."
The Octagon’s former library was also used for the Child Genius TV series earlier this year as a competition venue.
Louise Murray, production manager for Wall to Wall, said: "The venue worked well with the style of programme and the hospitality team were a great assistance throughout."
