Westminster is a government district, based in London, which was the former administrative capital of the Kingdom of England and is today part of the wider City of Westminster on the north bank of the River Thames. It is home to one of the highest concentrations of visitor attractions and historic landmarks in London, including: the Palace of Westminster, Buckingham Palace, Westminster Abbey and Westminster Cathedral. Historically the area lay within St Margaret's parish, City and Liberty of Westminster, Middlesex. The name Westminster originated from the informal description of the abbey church and royal peculiar of St Peter's , located west of the City of London . 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 , and from 1707 the British Government. In a government context, Westminster often refers to the Parliament of the United Kingdom, located in the UNESCO World Heritage Palace of Westminster — also known as the Houses of Parliament. The area is the centre of Her Majesty's 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. The area has a substantial residential population. By the 20th Century Westminster has seen rising numbers of residential apartments with wealthy inhabitants. Hotels, large Victorian homes and barracks exist near to Buckingham Palace.
