The sculptural space is located next to the National Library, in Mexico City. The original idea included the possibility of combining ecology and art, whereby seven university artists, researchers of aesthetic geometry, were selected to carry out the work.
The artists responsible for the work were Federico Silva, Manuel Felguérez, Helen Escobedo, Hersúa, Sebastián, Mathias Goeritz and Roberto Acuña, who sculpted the model that served as the basis for its construction on a natural scale.
The guiding model of the project is based on the following schemes: reproducing the cosmic image of the prehispanic world represented by a circle, whose perimeter was concentrated as a circle of 120 meters in diameter composed of 64 giant reinforcements.
The area of the circumference was constituted by the still sea of lava in its natural state and around the circle was determined to add a garden formed by the flora of the site.
The center of the sculptural space was inaugurated on April 23, 1979 and to the side was installed a metal plate with a reflection by José Vasconcelos.
Aiming to the south of the space and crossing the Maestro Mario de la Cueva circuit, several sculptures created by the university artists responsible for the project are geometrically dispersed. Among the sculptural works that embellish this zone are the following: The snakes of the Pedregal and Ocho rabbit, of Federico Silva; Ave two, of Hersua; Coatl, by Helen Escobedo; Colotl, by Sebastián; Corona del Pedregal, by Mathias Goeritz and Kepler’s key, by Manuel Felguérez.
