A−
HistoryA character grade: shown, never part of Socorro’s overall grade.
New Mexico towns list about as much on the Register as the country (a typical New Mexico town has 2.2 per 10,000 residents, the U.S. 2.4), so Socorro’s 23.6 sits above most of its state (79% of New Mexico towns have fewer) while its 20 historic buildings outnumber those of 79% of U.S. towns.
NoteThe founding year comes from Wikidata alone; no second source gives 1598.

What stands out about Socorro’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In June 1598, Juan de Oñate led a group of Spanish settlers through the Jornada del Muerto, an inhospitable patch of desert that ends just south of the present-day city of Socorro. As the Spaniards emerged from the desert, Piro Indians of the pueblo of Teypana gave them food and water. Therefore, the Spaniards renamed this pueblo Socorro, which means "help" or "aid". Later, the name "Socorro" would be applied to the nearby Piro pueblo of Pilabó.
Nuestra Señora de Perpetuo Socorro, the first Catholic mission in the area, was probably established c. 1626. Fray Agustín de Vetancurt would later write that around 600 people lived in the area during this period. Mines in the Socorro mountains were opened by 1626.
