London is the capital of both England and the United Kingdom, and is one of the world's major global cities. It has a long history dating back to its founding by the Romans. Greater London contains four World Heritage Sites that showcase its rich history and culture: the Tower of London, the historic settlement of Greenwich, the Royal Botanic Gardens at Kew, and the Palace of Westminster and Westminster Abbey.

10. The Collegiate Church of St Peter at Westminster, informally Westminster Abbey, is a large, mainly Gothic church, in Westminster just to the west of the Palace of Westminster. It is the traditional place of coronation and burial site for English, later British and later still Monarchs of the Commonwealth Realms. It briefly held the status of a cathedral from 1546–1556, and is currently a Royal Peculiar.
