The Espacio Escultórico at UNAM, a 1979 work of land #art by Helen Escobedo, Manuel Felguérez, Mathias Goeritz, Hersúa, Sebastián and Federico Silva, is one of the most extraordinary places I’ve ever been. The lenses on this phone are entirely inadequate to its scale, and these pictures in no way convey the feeling of being there. The most amazing bit is that I’d never heard word one of its existence before yesterday morning. A must-see in Mexico City.
