The British Museum in Great Russell Street, Bloomsbury, London is unique amongst world major museums and could take a whole week just to see all its exhibits. We suggest you specialise in a particular area that you are interested in and stick to that. To paraphrase their website “The British Museum’s collection of seven million objects represents the rich history of human cultures. In no other museum can the visitor see so clearly the history of what it is to be human”.
It was founded in 1753 by Act of Parliament after the death of Sir Hans Sloane (1660–1753). The wealthy physician, naturalist and collector had gifted his seventy thousand plus objects to the state in his will and this became the core of the early collection. It has continued to grow ever since with objects from around the globe.
It is free to enter, open every day and one of the great wonders of the world. The nearest Underground stations are Tottenham Court Road or Holborn. The website is vast and will give you a great idea on what to see and what special exhibitions are on at any particular time.
