The Basilica of the Immaculate Conception in Mazatlán, Sinaloa, holds a unique place in Mexico's religious history due to its rare Jewish influence in the construction of a Catholic church. During its completion in the late 19th century, Mazatlán’s Jewish community contributed significantly to the basilica’s development. Most notably, the Star of David appears in the stained glass windows, a symbol of appreciation for the Jewish community’s financial support during the building’s final phases.

This cooperation between the Catholic Church and the Jewish community was unusual for the time and reflects the multicultural fabric of Mazatlán in the late 1800s, a port city that was a melting pot of various cultures and religions. The incorporation of Jewish symbolism into a Catholic basilica is a testament to the collaborative spirit that allowed different communities to coexist and contribute to the city's development. This piece of history gives the basilica an added layer of cultural richness, making it a symbol of unity and mutual respect in Mazatlán’s diverse heritage.
