The sculpture rests directly atop a field of solidified lava created by the Xitle volcano eruption approximately 2,000 years ago.
The installation was a collaborative project involving six prominent Mexican artists: Helen Escobedo, Manuel Felguérez, Mathias Goeritz, Hersúa, Sebastián, and Federico Silva.
The 64 concrete prisms forming the ring are mathematically calculated to appear uniform from the center despite the irregular natural terrain.
The site acts as a gateway to the larger UNAM Ecological Reserve, which protects endemic flora and fauna of the Pedregal ecosystem.
It is recognized as one of the most significant pieces of contemporary land art in Latin America.
The Espacio Escultórico is a monumental outdoor land art installation inaugurated in 1979 within the UNAM ecological reserve. It features a large-scale circular base of volcanic rock topped by concrete prisms arranged in a geometric ring. The structure frames the surrounding landscape of the Pedregal de San Ángel, emphasizing the relationship between contemporary sculpture and the natural volcanic terrain. Designed through a collaboration of artists including Helen Escobedo, Manuel Felguérez, and Mathias Goeritz, the site occupies a site-specific ecological zone. The work centers on a circular plaza 120 meters in diameter, creating a rhythmic interaction with the jagged lava rock horizon. The site serves as a prime example of integration between 20th-century Mexican modernism and environmental preservation.

Wear sturdy, closed-toe walking shoes to navigate the uneven and sharp volcanic rock terrain.
Bring sun protection, as the site is almost entirely exposed to the elements with very little natural shade.
Carry a water bottle, as there are no vendor facilities immediately adjacent to the sculpture.
Attempting to traverse the surrounding lava fields beyond the designated trails, as the volcanic rock is brittle and sharp.
Access is generally restricted to the operating hours of the UNAM campus; it is occasionally closed for maintenance or during significant weather events.
Stay on marked paths to avoid damaging the protected ecological reserve; do not climb on the volcanic rocks.
