81 Newgate Street

81 Newgate Street, also known as Panorama St Paul’s, is a prominent 10-storey office building located in the City of London, directly opposite St Paul's tube station. Opened in June 1984, it served as the global headquarters for BT Group until December 2021. The building, designed in a modern style with Portland stone and granite facings, has a rich history, including being the site of Guglielmo Marconi's first public wireless transmission in 1897. Currently undergoing significant redevelopment, it will soon house HSBC and feature flexible office spaces, retail units, and a rooftop garden with a restaurant, enhancing its appeal for both tourists and researchers interested in London's architectural evolution and telecommunications history.
