The artwork is situated in Parc Jean-Drapeau, on St. Helen’s Island. The two openings that it creates enable viewers to contemplate downtown Montréal from one side and Parc Jean-Drapeau from the other.

The sculpture, made of red-painted steel, is composed of three columns linked by a diagonal element, offering a repetition of shapes from the principle of a deconstructed geometric form. The positioning of the columns follows a mathematical rhythm based on the number 7. The artwork presents elements of classical architecture and forms with a historical connotation (colonnade, coping). The vertical elements form two gateways that symbolize trade, universal access, circulation of ideas, and openness.

The artwork was given to the Ville de Montréal by Mexico City on the occasion of the celebrations for the 350th anniversary of Montréal. The site chosen underlines the signature of the North America Free Trade Agreement: the artwork is within the axis of Man, Three Disks by the American sculptor Alexander Calder and Phare du Cosmos by Yves Trudeau, bringing together artists from the three signatory countries.
