Smith Square, Square in Westminster, London, United Kingdom

Smith Square is a square in Westminster, London, with a garden interior mostly filled by St John's, Smith Square, a Baroque church converted into a concert hall. The surrounding buildings are mostly offices for government-related organizations, and the square has a mix of pedestrian and vehicle access on its sides.

The square was developed in the early 18th century on land owned by the Smith family, with Sir James Smith arranging its building around 1726. In the mid-20th century, it hosted the headquarters of the two largest British political parties, and later became home to government departments.

The square's name comes from the Smith family, who owned the land, and this history is reflected in the street signs and local references. Today, the area is a hub for political and environmental organizations, giving it a working atmosphere rather than a touristy one.

The square is easy to reach on foot from nearby landmarks, and its central location makes it a convenient stop while exploring the area. Visitors can walk around the square and its immediate surroundings, but access to the church and office buildings may be limited to certain hours.

Number 36, Mulberry House, contains one of London's most important Art Deco interiors, designed by Darcy Braddell. The building once housed the sculpture 'Scandal' by Charles Sargeant Jagger, which is now in the Victoria and Albert Museum.
