The Bank of England (formally the Governor and Company of the Bank of England) is the central bank of the United Kingdom and the model on which most modern central banks have been based. Established in 1694, it is the second oldest central bank in the World (the oldest being the Sveriges Riksbank (Bank of Sweden), established in 1668). The Bank's headquarters has been located in London's main financial district, the City of London, on Threadneedle Street, since 1734. It is sometimes known by the metonym The Old Lady of Threadneedle Street or simply The Old Lady, a name taken from the legend of Sarah Whitehead, whose ghost is said to haunt the bank's garden. The busy road junction outside is known as Bank junction. The Bank is one of eight banks authorised to issue banknotes in the United Kingdom, but has a monopoly on the issue of banknotes in England and Wales and regulates the issue of banknotes by commercial banks in Scotland and Northern Ireland.
