There are more than 400 public artworks in the City of Westminster, a borough in central London. Those discussed in this article include freestanding statues, busts and other kinds of permanent sculpture, memorials (excluding plaques without a sculptural element on buildings), fountains, murals, gates and exterior mosaics in the City of Westminster, except for those in the former metropolitan boroughs of Paddington and St Marylebone and in two of the Royal Parks of London, namely Hyde Park and Kensington Gardens. Separate articles list works in the aforementioned areas and architectural sculpture across the borough.
There is more public sculpture in the City of Westminster than in any other area of London. This reflects the borough's central location containing most of the West End, the political centres of Westminster and Whitehall and three of the Royal Parks (Green Park, Hyde Park and St James's Park, with parts also of Regent's Park and Kensington Gardens). Many of the most notable sites for commemoration in London are to be found in the City of Westminster, including Trafalgar Square, Parliament Square and the Victoria Embankment. Other monuments of note in the borough include the Albert Memorial and the Victoria Memorial. After World War I many memorials to that conflict were raised in the area, the most significant being the Grade I-listed Cenotaph in Whitehall. So great is the number of monuments in the borough that Westminster City Council has deemed an area stretching from Whitehall to St James's to be a "monument saturation zone", where the addition of new memorials is generally discouraged. The same restriction applies in Royal Parks within the borough.
