Named after the 3rd Duke of Portland, the unusually wide street is home to the BBC's headquarters Broadcasting House, the Chinese and Polish embassies, the Royal Institute of British Architects and numerous residential mansion blocks.
The street was laid out by the brothers Robert and James Adam for the Duke of Portland in the 1770s and originally ran north from the gardens of a detached mansion called Foley House.
[5] While most is high quality residential in a close local community, many of the houses are now occupied by company headquarters, professional bodies, embassies and charities (including Arthritis Research UK and the Royal Air Force Benevolent Fund).
The landmark headquarters of the Royal Institute of British Architects sits at 66 Portland Place directly opposite the Chinese embassy; for years practitioners of Falun Gong have mounted a silent protest in front of the former and facing the latter.
A Grade II listed memorial to Quintin and Alice Hogg erected in 1906 stands opposite Broadcasting House at the south end of Portland Place.
