Westminster () is an area of central London within the City of Westminster on the north bank of the River Thames. Westminster’s concentration of visitor attractions and historic landmarks, one of the highest in London, includes the Palace of Westminster, Buckingham Palace, Westminster Abbey and Westminster Cathedral. Historically the area lay within St Margaret’s parish, City & Liberty of Westminster, Middlesex. The name Westminster originated from the informal description of the abbey church and royal peculiar of St Peter’s (Westminster Abbey’s), literally West of the City of London, indeed until the Reformation there was a reference to the ‘East Minster’ at Minories (Holy Trinity Priory, Aldgate) east of the City; the abbey was part of the royal palace that had been created here by Edward the Confessor. It has been the home of the permanent institutions of England’s government continuously since about 1200 (High Middle Ages’ Plantagenet times) and is now the seat British government. In a government context, Westminster often refers to the Parliament of the United Kingdom, which is located in the UNESCO World Heritage Palace of Westminster – also known as the Houses of Parliament. The closest tube stations are Westminster, St James Park on the Jubilee and Circle and District lines. The area is the centre of UK government, with Parliament in the Palace of Westminster and most of the major Government ministries known as Whitehall, itself the site of the royal palace that replaced that at Westminster. Within the area is Westminster School, a major public school which grew out of the Abbey, and the long established University of Westminster, attended by over 20,000 students. Bounding Westminster to the north is Green Park, a Royal Park of London.
