Portland Place is a street in the Marylebone district of central London.
It was laid out for the Duke of Portland in the late 18th century. It originally ran north from the gardens of a detached mansion called Foley House. The street is particularly wide, at 33 metres. Apparently it was designed this way so as not to interfere with Lord Foley’s views to the north.
Today Portland Place still contains many spacious Georgian terraced houses, as well as some early 20th century buildings, and houses a number of company headquarters, professional bodies, embassies and charities.
