Confused sightseers have been turning up at a computer shop in Windsor in the mistaken belief it is Windsor Castle.
Castle PC gets up to 20 phone calls a day for the Queen's residence and many visits from bemused tourists.
Co-owner Seb Smith, said the problem was caused by Google. When the words 'Windsor Castle' are typed in, a map to the shop, in Windsor, Berks, appears in the top searches.
Seb, 36, said: 'This summer we had people coming in saying we do not look like the castle. Many are American tourists and I have to give them directions.'
According to the Daily Mirror, Google is said to be investigating the mix-up.
