The City Hall of Toronto, Ontario, Canada is the home of the city's municipal government and one of its most distinctive landmarks. Designed by Finnish architect Viljo Revell (with Heikki Castrén, Bengt Lundsten, Seppo Valjus) and landscape architect Richard Strong, and engineered by Hannskarl Bandel, the building opened in 1965. It was built to replace Old City Hall, which was built in 1899. The current City Hall, located at Nathan Phillips Square, is actually Toronto’s fourth city hall and was built in order to replace the former city hall due to a shortage of space. The area of Toronto City Hall and the civic square was formerly the location of Toronto's old chinatown, which was expropriated and bulldozed during the mid-1950's in preparation for a new civic building.

In 1958, an international architectural competition was launched by Mayor Nathan Phillips in order to find a design for the New City Hall. This competition was won by Finnish architect Viljo Revell whose winning proposal came first amongst submissions from forty-two countries. Revell’s design consists of twin towers surrounding a white disk-like council chamber which is mounted on a raised platform, with entrances located below that are open to the public. There is also a ramp from the square that connects to the podium green roof and also leads to the council chamber. The two towers are of unequal height as the east tower is taller than the west. The City Hall is nicknamed “The Eye of the Government” because it resembles a large eye in a plan view. Revell died a year before the New City Hall was completed.
