The Fourth Plinth stands in the north west corner of Trafalgar Square. Built in 1841 it was originally intended to act as the base of a statue of the typical Victorian hero - soldier or sailor - as its three companions in the square have always done.
In modern times there has been heated debate as to whose statue it should support but now it could be any one of us. The sculptor Antony Gormley is asking the people of the UK to occupy the Fourth Plinth for one hour at a time. He sees this as a representation of the whole of humanity. Every hour, 24 hours a day for 100 days, individuals who will be selected at random from all applicants can make the Plinth their own.
So does this make us all potentially heros? And how might the Heritage Wardens who are on duty in Trafalgar Square 24 hours a day describe us to the tourists who come to visit?
