This famous London Square was designed by Charles Barry in the Italian Style. The design was modified in 2002-3, when the north side of the Square was pedestrianised, by making a central flight of steps leading down from the National Gallery to the fountains. The lions which overlook the fountains were designed by Sir Edwin Landseer. It is a popular place for demonstrations. Some 2,000 square metres of turf was laid in Trafalgar Square for 2 days in May 2007 to promote green spaces and villages in London.
