Located in the City of Westminster, it is part of the Tyburnia area north of Hyde Park.

Tyburnia was developed in the first half of the nineteenth century, providing upmarket residential streets and squares for the expanding population of London.

[1] While many other streets in the area feature white stuccoed buildings that once would have been commonplace on Sussex Square, it was heavily redeveloped in the twentieth century.

Winston Churchill, the future Prime Minister, lived at 2 Sussex Square in the early 1920s.
