San Ángel is a colonia or neighborhood of Mexico City, located in the southwest in Álvaro Óbregon borough. Historically, it was a rural community, called Tenanitla in the pre-Hispanic period. Its current name is derived from the El Carmen monastery school called San Ángel Mártir. San Ángel remained a rural community, centered on the monastery until the 19th and 20th centuries, when the monastery was closed and when the area joined urban sprawl of Mexico City. However, the area still contains many of its former historic buildings and El Carmen is one of the most visited museums in the city.
