In the mid-1940s
Luis Barragán began a project to urbanize the area and protect its ecosystem. Barragán had the idea of developing El Pedregal promoting the
harmony between architecture and landscape. The first structures built on the site were the Plaza de las Fuentes, or Plaza of the Fountains, the demonstration gardens and demonstration houses by Barragán and
Max Cetto. Other famous architects that contributed to the development of Pedregal include: Francisco Artigas, Manuel Parra, Enrique Castañeda Tamborrell, José María Buendía, Antonio Attolini, Fernando Ponce Pino, Óscar Urrutia, and Manuel Rosen.“Los Jardines del Pedregal de San Ángel, un legado de la modernidad arquitectónica 1947-1962”
Plaza de las Fuentes El Pedregal's original main entrance, the Plaza de las Fuentes, was completed by the second half of 1949, and was located at the intersection of Fuentes and San Jerónimo avenues. The only remaining element of the plaza is the magnificent concrete
Animal del Pedregal a sculpture by
Mathias Goeritz, inspired by a prehistoric animal figure etched into the rocks of the Pedregal.
Model Gardens and Casas Muestra The Model Gardens were designed by Luis Barragán for public inspection and planned as models for the development of private space. The Casas Muestra were intended for publicity and sales purposes. The first one was built in 1950 according to the project by Max Cetto in collaboration with Luis Barragán (Av. Fuentes 130). Next to it, on Av. Las Fuentes 140, followed the home acquired by the painter
Roberto Berdecio and designed by Max Cetto in 1951. Along with these residences, the Model Gardens were intended to entice prospective buyers and demonstrate the Pedregal's potential as a site for garden-homes. They were to illustrate Barragán's idea of
correct building, promoting the sort of
harmony between architecture and landscape that Barragán desired. Occupying about , these gardens were enclosed by volcanic-stone walls and iron fences and entered through metal or rough-hewn wood gates. During summer evenings in the 1950s, classic Spanish plays, produced by Barragán and the painter and sculptor
Juan Soriano, were performed here for the general public. ==Today==
