Q:Information: - The River Fleet is the largest of London's subterranean rivers. Its headwaters are two streams on Hampstead Heath, each of which was dammed into a series of ponds, the Hampstead Ponds and the Highgate Ponds, in the 18th century. At the southern edge of Hampstead Heath these descend underground as sewers and join in Camden Town. The waters flow from the ponds to the River Thames. - Ludgate Circus is a road junction in the City of London where Farringdon Street and New Bridge Street (together forming part of the A201 road) cross Fleet Street and Ludgate Hill (which rises up to St Paul's Cathedral). - London Wall was the defensive wall first built by the Romans around Londinium, their strategically important port town on the River Thames in what is now London, England, and subsequently maintained until the 18th century. - Central London is the innermost part of London, England. There is no official definition of its area but its characteristics are understood to include a high density built environment, high land values, an elevated daytime population and a concentration of regionally, nationally and internationally significant organisations and facilities. Over time a number of definitions have been used to define the scope of central London for statistics, urban planning and local government. - The City of London is a city and county within London. It constituted most of London from its settlement by the Romans in the 1st century AD to the Middle Ages, but the agglomeration has since grown far beyond the City's borders. The City is now only a tiny part of the metropolis of London, though it remains a notable part of central London. Administratively, it forms one of the 33 local authority districts of Greater London; however, the City of London is not a London borough, a status reserved for the other 32 districts (including London's only other city, the City of Westminster). - A borough is an administrative division in various English-speaking countries. In principle, the term "borough" designates a self-governing walled town, although in practice, official use of the term varies widely. - Fleet Street is a major street in the City of London. It runs west to east from Temple Bar at the boundary with the City of Westminster to Ludgate Circus at the site of the London Wall and the River Fleet from which the street was named. - The City of Westminster is an Inner London borough which also holds city status. It occupies much of the central area of Greater London including most of the West End. It is to the west of and adjoining the ancient City of London, directly to the east of the Royal Borough of Kensington and Chelsea, and its southern boundary is the River Thames. It was created with the 1965 establishment of Greater London. Upon creation, Westminster was awarded city status, which had been previously held by the smaller Metropolitan Borough of Westminster. - London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly. - In the history of Europe, the Middle Ages or medieval period lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. - Westminster is an area of central London within the City of Westminster, part of the West End, 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. - Bouverie Street is a street in the City of London , off Fleet Street , which once was the home of some of Britain 's most widely circulated newspapers as well as the Whitefriars Priory . The offices of the News Chronicle , a British daily paper , were based there until it ceased publication on 17 October 1960 after being absorbed into the Daily Mail . The News of the World had its offices at No. 30 until the paper 's closure in 2011 ; its sister paper The Sun is still based there . It was also home to the offices of Punch magazine until the 1990s and for some decades of Lutterworth Press , one of Britain 's oldest independent publishers celebrated for Boy 's Own Paper and its sister Girl 's Own Paper . The street 's name comes from the landlords of the area , the Pleydell - Bouveries , Earls of Radnor . What entity does 'bouverie street' has the relation 'instance of' with?
