The cathedral has been rebuilt multiple times since 1580, with the current structure dating back to the mid-18th century.
The facade contains a 19th-century sculptural relief depicting the reunion of Joseph with his brothers in Egypt, interpreted as a symbol of national unity.
The mausoleum of José de San Martín is flanked by three female statues representing Argentina, Chile, and Peru.
The cathedral contains the remains of the Unknown Soldier of Independence.
It holds a 17th-century wooden image of Christ known as 'Santo Cristo de Buenos Aires' which is considered the oldest sculpture in the city.
The floor design contains a large cross of Jerusalem, symbolizing the historical link to the Holy Land.
The cathedral's pipe organ is one of the largest in South America, built by the Walcker firm in Germany.
The tomb of San Martín is strategically placed in a side chapel so that it remains visible from the main entrance, unlike traditional burials which are usually in the crypt.
The Buenos Aires Metropolitan Cathedral is the main Catholic church in Argentina, serving as the seat of the Archbishop of Buenos Aires. Its most distinct architectural feature is the lack of traditional bell towers, replaced by a massive 12-column Neoclassical facade modeled after the Palais Bourbon in Paris. The interior houses the mausoleum of General José de San Martín, the hero of Argentine independence, guarded by soldiers of the Regiment of Mounted Grenadiers. A flame burns perpetually in front of the tomb to commemorate the liberation of Argentina, Chile, and Peru. The cathedral features an opulent interior with an Italian marble floor and a central nave that spans nearly 100 meters. The altarpiece of the main altar was carved by Pedro de Acosta in 1785. The cathedral was declared a National Historic Monument in 1942. Pope Francis, formerly Cardinal Jorge Mario Bergoglio, served as the Archbishop of Buenos Aires here before his election to the papacy in 2013.

Walk slowly around the perimeter of the interior to view the varied devotional art in the side chapels.
Visit the dedicated small museum behind the main altar for historical religious artifacts and papal memorabilia.
Take time to examine the floor tiles, as they feature intricate geometric patterns and early colonial motifs.
Do not attempt to enter through the main doors if a liturgical service or mass is currently in progress, as entry for tourists is restricted during these times.
Maintain a low voice and respectful demeanor; shoulders and knees should be covered as a sign of respect for a functioning place of worship.
