Dubbed "a urinal for the Jolly Green Giant" by some critics, Toronto's newest city hall was the outgrowth of a 1958 international competition. A remarkable mural within the main entrance, Metropolis, was constructed by sculptor David Partridge from 100,000 common nails. In front of the building is Nathan Phillips Square, a gathering place. Annual events at New City Hall include the Spring Flower Show in late March; the Toronto Outdoor Art Exhibition early each July; and the yearly Cavalcade of Lights from late November through Christmas, when 100,000 sparkling lights are illuminated across both city halls. The underground garage holds 2,400 cars.
