The cathedral was established as a temporary structure after the 1861 earthquake but was later elevated to a permanent cathedral status in 1934.
Its construction utilizes reinforced concrete, a departure from the adobe and stone methods used in the city's pre-1861 architecture.
The interior contains a notable stained-glass cycle depicting themes relevant to local Marian devotion.
It replaced the ruins of the original Jesuit church, which had served the city's inhabitants since the colonial era.
The cathedral serves as the final resting place for several significant local religious figures and pioneers of the Mendoza diocese.
Our Lady of Loreto Cathedral serves as the ecclesiastical seat of the Archdiocese of Mendoza, Argentina. It is a modern-style architectural structure constructed following the destruction of the city's original colonial cathedral in the 1861 earthquake. The building features a prominent, austere facade and a minimalist interior design characteristic of mid-20th-century religious architecture in the region. It houses the remains of General José de San Martín's companion, Friar Luis Beltrán, though historical interpretations of these relics vary. The cathedral functions as a primary site for significant liturgical celebrations and archdiocesan events in Mendoza. Its location on José Federico Moreno street places it within the city's urban grid, a few blocks east of the central business district.
The central aisle looking toward the altar captures the clean, symmetrical geometry of the interior nave.
