This was our joint proposal together with Pedro Ramírez Vázquez, for a national competition that aimed to commemorate Mexico’s bicentennial of its Independence with. The Ring is formed by a loop built on the principle of a Moebius strip one hundred meters in diameter and with a cross-section of ten meters at its structural axis, perpendicular to Reforma Avenue. The landmark’s lower part remains underground, in such a way that three spaces are generated: the Ring itself; an area below ground level with the dual role of pedestrian walkway and Historical Memory Site, at the monument’s base; and a plaza or public space that consists of two amphitheaters, one on each side of the irregular oval formed by the Historic Site and the pedestrian walkway in the polygon delimited by the existing urban and architectural elements on the sides of Reforma Avenue.
It’s the first time that such a proposal has been attempted: the construction of a monumental circlet following the logic of a Moebius strip, the defining characteristic of which is its essential unity. Unlike a simple circle, which has two opposing faces that will never touch—internal and external—the Moebius strip has a single continuous face that is two-dimensional at every point. Duality is maintained, but the surface may be followed from any location until the other side is reached. Whatever point one starts from, the two sides eventually come together, converting the Bicentennial Ring into a meeting place.
