A red postbox that mysteriously appeared in the middle of a bridge is going to be removed.
The postbox appeared a few weeks ago on the side of Sonning Bridge, which crosses the River Thames in Berkshire.
Royal Mail said the postbox is not real and any letters posted would not get delivered.
People living nearby say the postbox is a mystery. Some people think it was put up as a piece of art.
Local councillor Mike Haines said he thought it was a "bit of fun" but the postbox will have to come down.
The Sonning Bridge is a "listed" structure which means it is protected and any alterations must be approved by the council.
