Pedregal is a vast swath of territory stretching across south-central Mexico City. The name originates with the lava flows of the Xitle Volcano (far to the south-southwest in the map). The lava flows created a unique and delicate environment protected in the Pedregal de San Ángel Ecological Reserve on the CU campus. The Bosque de Tlalpan, also referred to as the Bosque de Pedregal, protects a similar environment to the south.
The name got an enormous boost in 1948 when architects Luis Barragán and José Alberto Bustamante laid out plans for an extensive, integrated housing tract. Over the next 25 years, this would evolve into a showcase of the country's most important residential architecture.
