Diana Teruggi, a student, and Daniel Mariani, a graduate student in economics, in 1975 moved with her only daughter Clara Anahí to la Plata, in a house on Calle 30 de, which also functioned as one of the Montoneros operating houses in that city. The clandestine press of the magazine Evita Montonera were hiding there. On November 24, 1976, the house was attacked for 3 hours by more than one hundred members of the Army and the
Buenos Aires City Police. All the adults who were there that day were killed. The others, Diana Teruggi, Roberto Porfidio, Daniel Mendiburu Eliçabe, Juan Carlos Peiris and Alberto Bossio, Clara Anahí Mariani, all were taken alive and kidnapped that day. The day of the attack Daniel Mariani had left the house for work in Buenos Aires. For about eight months he fought for the organization Montoneros clandestinity. On August 1, 1977, he was murdered while he was with her fellow militant Laura Carlotto. On the walls and ceilings of Mariani-Teruggi House, you can still see the impact of the bullets and the blood of the people murdered there. In 1998, the house was recovered and was opened to the public. The same year the house was declared of Municipal Interest and
Cultural Heritage of the
Province of Buenos Aires in 2000, and also declared of
National Interest in 2003, and declared a National Historical Monument in 2004.
