On April 23, 1979, the sculpture space was inaugurated where the sculptures created by the artists involved in that sculpture project are dispersed in a geometric way.[2]​.

Joaquín Sánchez MacGregor, in his speech at the inauguration of this sculptural space, said the following: "This sundial, telluric mandala; this pre-Hispanic ceremonial center of the 20th century, spectacle for spectacles, susceptible to multiple readings and functions, was born under the sign of the unity of opposites, of love for a change that, precisely because it is such, is nourished by the best traditions, so diverse among themselves, of industrial or technological art, of Mexican muralism in its public dimension, of formal and community values. that the pre-Columbian complexes today desacralized display".[4]​.

The work consists of a surface of natural terrain of the Pedregal, formed by the solidified lava of the Xitle volcano, without vegetation and enclosed in a circular platform composed of a platform and a series of geometric modules placed on it. The outer diameter measures 120 meters and the inner diameter 92.78 meters.

The platform is built based on two volcanic stone walls, which contain ballast filling, to obtain a permeable stone fill. The height of the walls varies due to the topography of the land (ranges between 50 centimeters and 9 meters). The surface is finished in tezontle grain, to maintain permeability and provide a touch of color.[5]​

On the platform, 64 polyhedral prisms with a rectangular base, measuring 9*3 meters, with a height of 4 meters, are erected. The arrangement of these modules is by quadrants, in each one there are 16 modules separated from each other by a distance of 1.75 meters on the interior perimeter, and on the exterior of 2.67 meters. The quadrants of the four cardinal points measure 3.60 meters on the inside perimeter and 4.80 meters on the outside, in such a way that where the cardinal points are marked there is a greater separation, clearly visible.

The modules were founded on a reinforced concrete slab. The walls of the vertical faces are also made of reinforced concrete, and precast concrete joists were placed on them that support hollow blocks of cement and sand. The surface of all faces had a thick hammering to provide the texture proposed by the sculptors.[4]​.
