The Bank of England has been at the heart of the country's
monetary system since 1694, and its magnificent headquarters is one
of the great sights of the City of London. Although it is,
understandably, not open to the public, it does boast a fascinating
museum, which is actually housed within the Bank itself, and
includes items from its vast archive along with artworks, examples
of banknotes over the centuries and much more. Free, and open from
Monday to Friday.
