El Rancho de las Golondrinas grew out of the vision of the Curtin-Paloheimo family, who acquired the property in the early 1930s. Existing historic buildings were restored, authentic structures erected on old foundations and related buildings brought in from other sites. Now, an 18th century placita house complete with defensive tower, a 19th century home and all of its outbuildings, a molasses mill, a threshing ground, several primitive water mills, a blacksmith shop, a wheelwright shop, a winery and vineyards depict many of the essential elements of Spanish Colonial culture. The Sierra Village portrays life as it was lived in the mountainous regions of New Mexico. A morada, descansos, a Campo Santo and an Oratorio testify to the deep religious faith that sustained the early settlers.

Through living history, El Rancho de las Golondrinas hopes to foster understanding of, respect for and pride in the language, culture and history of Spanish Colonial New Mexico. Particular emphasis is placed on its use as an educational facility. It welcomes teachers and students for tours, workshops, seminars and other learning experiences. The museum is now owned and operated by the El Rancho de las Golondrinas Charitable Trust, a non-profit entity. It is a member of the Association for Living Historical Farms and Agricultural Museums (ALHFAM).
