## History

Noria de Ángeles is situated in an area that was originally inhabited by the Guachichil, one of the Chichimeca nations. The settlement of Noria de Ángeles was first registered on 15 January 1621, and the mining settlement of Real de Ángeles was recorded in 1705.
The municipality of Angeles was established in the partido of Pinos on 29 October 1833. It became a free municipality under the name of Noria de Ángeles on 19 August 1916. From 1935 to 1941, the municipality was named after Álvaro Obregón.
The Temple of Nuestra Señora de los Ángeles was built in Noria de Ángeles from 24 June 1870 to August 1872. It was inscribed on the UNESCO list of World Heritage Sites in 2010 as part of the Camino Real de Tierra Adentro.
In 1979, the village of Real de Ángeles was demolished and rebuilt 5 kilometres (3.1 mi) to the east to make way for an open-pit silver mine. The world's largest such mine in the 1980s, it was operated from 1982 to 1998 by Grupo Frisco, a mining company owned by Carlos Slim. Grupo Frisco has been repeatedly sanctioned for failing to comply with environmental regulations during the mine's operation and closure. The full extent of the mine's impact on the local environment and the health of the local population has yet to be thoroughly investigated.
