What stands out about Bernalillo’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Bernalillo is one of the oldest European-founded communities in New Mexico. The area had been occupied for centuries by indigenous Pueblo peoples before Spanish resettlement in the late 17th century. Following the Spanish reconquest of New Mexico, Governor Diego de Vargas founded the settlement of Bernalillo in 1695, and the community developed along the Rio Grande as part of the colonial corridor associated with El Camino Real de Tierra Adentro. Bernalillo later grew from a series of riverfront haciendas into a regional trading center linking nearby Pueblo communities and Hispanic settlers.
In 1698, according to Wikidata. Bernalillo’s post office opened in 1855, and the census of 1880 counted 1,223 people here.
