The basilica is located on the oldest part of the city, at the corner of Buenos Aires St. and Córdoba St., besides the "Palacio de los Leones" (that is, the municipal building), across the pedestrian path called "Pasaje Juramento" ("Oath Passage") that leads into the National Flag Memorial. The basilica faces "Plaza 25 de Mayo" (May 25th Square), also bordered by the Central Post Office.
