To the north, in front of the back of the Cathedral, is the small but historic Plazoleta del Fundador with a patinated bronze sculpture representing Jerónimo Luis de Cabrera standing.
In 1598 the master builder Gregorio Ferreira and the stonemason Juan Rodríguez undertook the construction of the building with sufficiently solid materials (stone, bricks and lime).
Giovanni Battista Primoli designed the main floor plan (Latin cross of the basilica type) following the model of the almost contemporary Jesuit Church of the Gesù in Rome.
Some of these include General José María Paz (and his wife, Margarita Weild), Dean Gregorio Funes, Bishop Hernando de Trejo y Sanabria (the first rector of the University of Córdoba, the oldest in Argentina), and Friar Mamerto Esquiú.
The interior was later decorated with frescoes and murals painted in the early years of the 20th century by Emilio Caraffa, Carlos Camilloni, and Manuel Cardeñosa.
Its interior is beautiful: the great central nave roofed with a high continuous barrel vault is profusely and harmoniously embellished by a large number of carved wood and gilt moldings -many of them in the gold leaf-, the main altar makes a balanced game with the high columns and the ancient sculptures that represent various Catholic saints.
The total set of the Argentine cathedral of Córdoba is an excellent synthesis of elements with Renaissance origins combined with those of the Spanish colonial Baroque, Neoclassicism and even Mudéjar details.
