Jardines del Pedregal (English: Rocky Gardens) or simply El Pedregal (full name: El Pedregal de San Angel) is an upscale residential colonia (neighborhood) in southern Mexico City hosting some of the richest families of Mexico. It is also known as the home to the biggest mansion in the city. Its borders are San Jerónimo Avenue and Ciudad Universitaria to the north, Insurgentes Avenue to the east and Periférico to the south and west. Its 510 hectares (1,250 acres) were a major real estate project undertaken by Mexican modernist architect Luis Barragán.
When it was originally developed, in the mid-1940s in the lava fields of the Pedregal de San Ángel, it was probably the biggest urban development the city had seen. The first house to be built here was the studio and home of architect Max Cetto.
The area has changed significantly since its original development. Although its modernist spirit and original elements of ecosystem protection are gone, critics have described its original houses and gardens as a turning point in Mexican architecture. Some of the old modernist houses have been catalogued as part of Mexico's national patrimony.
