Westminster is the main settlement of the City of Westminster in London, England. It extends from the River Thames to Oxford Street and has many famous landmarks, including the Palace of Westminster, Buckingham Palace, Westminster Abbey, Westminster Cathedral, Trafalgar Square and much of the West End cultural centre including the entertainment precinct of West End Theatre.

St James's is a central district in the City of Westminster, London, forming part of the West End. The area was once part of the northwestern gardens and parks of St. James's Palace. During the Restoration in the 17th century, the area was developed as a residential location for the British aristocracy, and around the 19th century was the focus of the development of their gentlemen's clubs. Once part of the parish of St Martin in the Fields, much of it formed the parish of St James from 1685 to 1922. Since the Second World War the area has transitioned from residential to commercial use.
