The Basilica of Our Lady of the Rosary and Convent of Saint Dominic is a Catholic church in Buenos Aires. In its atrium rest the remains of Manuel Belgrano and other Argentine national heroes. The Dominicans occupied the site since 1606, but the current construction began in 1751, designed by Antonio Masella. Work resumed in 1762 with the support of Juan de Lezica and the church was consecrated in 1783, still unfinished. The convent was started in 1792 and completed in 1805. During the British Invasions in 1806, General Liniers promised to donate captured flags if the city was retaken — a promise he fulfilled. These flags are still preserved in the church. In 1807, during the second invasion, the convent was the site of the Battle of Santo Domingo. The British used its tower as a stronghold until they were defeated. During its reconstruction, wooden plugs were placed to commemorate the bullet impacts from that battle.

The Buenos Aires Customs House, located at 350 Azopardo Street, is the headquarters of the General Customs Directorate and was declared a National Historic Monument in 2009. Its origins date back to 1580, but it did not have its own building until centuries later. It operated in various rented locations, including the house of Domingo Basavilbaso (1783–1858), and later in the Taylor Customs House (1858–1896), which was demolished to make way for the construction of Puerto Madero. Due to the need for a modern building, a new one was planned on land reclaimed from the river. The design was by the Lanús and Hary studio in 1908, and construction began in 1909. It was inaugurated in October 1910 during the Centennial celebrations, although it began to be occupied in January 1911. The formal handover of the building took place in 1913, and the work was fully completed in 1915. It is considered an icon of Argentine institutional architecture.

The Pontifical Catholic University of Argentina, officially *Pontificia Universidad Católica Argentina Santa María de los Buenos Aires* (UCA), is a private, religiously affiliated university headquartered in Puerto Madero, Buenos Aires. Its origins trace back to the Catholic University of Buenos Aires (1910–1922), which closed due to the lack of official recognition for its degrees. In 1922, the *Catholic Culture Courses* (C.C.C.) were established, considered the intellectual foundation of the UCA. These courses offered training in philosophy, economics, and the arts, promoting a Catholic and anti-liberal worldview. They were led by figures such as Tomás Darío Casares and included renowned professors like Derisi, Etcheverry Boneo, and Dell'Oro Maini. The original headquarters was on Reconquista Street, and the program also published academic and opinion works. Notable figures such as Onganía, Goyeneche, Bernárdez, and Marechal were associated with the C.C.C.

It is the architect’s first work in Latin America and symbolizes a couple dancing tango.

The Casa Rosada is the seat of the Argentine Executive Branch, located at 50 Balcarce Street, facing Plaza de Mayo.

It was built on the site of the old Buenos Aires fortress, originally constructed in 1594 and later modified by successive governments. In the 19th century, President Sarmiento had it painted pink — a color symbolizing the unity between Unitarians and Federalists, though also used for technical reasons. In 1873, the Post Office Palace was planned and completed in 1879. Later, to unify the two buildings, architect Tamburini designed the iconic monumental arch, with construction starting in 1886.
