Thick adobe walls rise ahead of you and belong to the Santuario de Nuestra Señora de Guadalupe, the oldest church in the United States dedicated to Our Lady of Guadalupe. It is listed on the New Mexico State Register of Cultural Properties and is a contributing property in the Santa Fe Historic District. The building you see is a simple cruciform church with thick adobe walls, a structure that has been remodeled several times and most recently in the 1970s.
Historical records place its construction sometime between the late 1700s and early 1800s: archdiocese records suggest a license was issued around 1795, though the church was not definitively documented until 1821; an older origin before the Pueblo Revolt of 1680 has been claimed but is probably apocryphal. Inside there is an altar screen depicting Our Lady of Guadalupe, transported in pieces from Mexico City over the Camino Real, signed by José de Alcíbar and dated 1783. The church remained active until the 1830s.
Notice the thick adobe walls forming this cruciform church, and picture the 1783 altar screen that once stood inside, carried here from Mexico City.
