Lonely Planet review
In many ways Trafalgar Sq is is the centre of London, where rallies and marches take place, tens of thousands of revellers usher in the New Year and locals congregate for anything from communal open-air cinema and Christmas celebrations to various political protests. it is dominated by the 52m-high Nelson's Column and ringed by many splendid building, including the National Gallery and St Martin-in-the-Fields.
The great square was neglected over many years, ringed with traffic and given over to flocks of feral pigeons fed by tourists and locals alike. In 2000 newly elected Mayor Ken Livingstone embarked on a new scheme to transform the square into the kind of space John Nash had intended when he designed it in the early 19th century. Traffic was banished from the northern flank in front of the National Gallery and a new pedestrian plaza built.
