Diego Portales Building / Villavicencio Tower
After the bombing and fire of the Palacio de la Moneda, as a result of the coup d'état of September 11, 1973, the building became the headquarters of the government. Decree Law No. 190 of December 10 of that year changed the name of the complex to “Diego Portales Building.” From 1973 to 1981, the Executive Branch (under the administration of Augusto Pinochet) and the Legislative Branch (made up of the Government Board "Junta de Gobierno de Chile (1973)") functioned there.[21] Other public organizations were also based there, such as the General Secretariat of Government, the Military House, the Ministry of the Interior, the National Commission for Administrative Reform (Conara) and the Division of Social Communication. (Dinacos). Various studies have confirmed that during the dictatorship of Augusto Pinochet, it was a headquarters and torture center for important or classified political prisoners, the most recognized being an 11-year-old boy, who was never identified, only his charred remains with five rifle wounds were found. Various visitors claim to have seen him hanging around the facilities, most frequently in the parking lots of the main building. Popular culture has baptized him as "The Little Angel".[22].
On March 11, 1981, when the presidential offices returned to La Moneda, the tower continued to be the headquarters of the Legislative Power, exercised by the Government Board, until the return to democracy "Transition to democracy (Chile)") in 1990.
During the first three Concertación governments (1990-2006), the plaque was used as a center for public and private conferences and conventions, and the tower was the headquarters of the Ministry of National Defense; Most of its departments were moved to the Civic District in 2007, but the 23 floors of the skyscraper—364 Villavicencio Street—remained in the hands of the Ministry, which was preparing to abandon it definitively at the end of 2014;[23] However, this took place with a delay of two years, at the beginning of 2017.[4]
In addition, during the elections it housed the computing center of the Ministry of the Interior. For the primary elections of June 30, 2013, the building was once again the Press Center, but this time in charge of the Electoral Service, which was installed in the Library of the Gabriela Mistral Cultural Center.[24].
Defensa continued to occupy the Villavicencio tower until 2016 and in January of the following year it finally transferred the building to National Assets. The minister of the sector, Nivia Palma, announced that it would become a space open to cultural and social organizations;[4] in April, Palma reported that the decision to grant a complete floor free of charge to the Víctor Jara Foundation in the building, which should be operational in the second half of 2017. Other organizations that expected free concessions in this Citizenship Building were the Chilean Human Rights Commission, the Villa Grimaldi Corporation, the Venda Sexy, the Corporación Humanas, the Corporación del Transplante and the Transplantado, the Children's Council or the Corporación Letras de Chile, in addition to possible spaces for residencies for artists from regions who carry out internships at the GAM.[25][26] However, a technical report from the Ministry of Public Works "Ministerio de Obras Públicas (Chile)") declared the tower uninhabitable, and in 2018 the minister of National Assets Felipe Ward reported that an eventual normalization of the complete structure would take between three or four years and close to $19,750 million.[27].
At 4:45 p.m. on March 5, 2006, a violent fire broke out, originating in the east wing of the convention center, which destroyed 40% of its structure. The plenary hall was completely destroyed, the white and blue hall were damaged by 25%. In addition, it caused the collapse due to the melting of the metal structure of the roof, half an hour after the fire broke out.[28] The fire mobilized 28 units of the Santiago Fire Department and kept the Alameda closed from Plaza Baquedano to Cerro Santa Lucía, in addition to suspending metro service at the Universidad Católica station "Universidad Católica (station)"), located under the building. The column of toxic smoke generated was visible from several points, while it was moved by the winds towards the eastern sector of Santiago. Finally, the fire was controlled after an hour of work.
The official report, delivered by the Santiago Fire Department, stated that the fire would have originated from an overheating in the electrical network, which was without maintenance, as a result of renovations that were being carried out in the underground on the eastern side. The Roberto Matta painting that adorned the interior was not damaged.
