“Mansión Seré” was one of approximately 340 clandestine detention centers where, during the military dictatorship, the armed forces carried out a systematic policy of kidnapping and disappearance of a still undetermined number of people. Mansión Seré was maintained between the end of December of 1976 and April of 1978 in an old mansion (situated in Blas Parera 48 -on the border between Ituzaingó and Castelar, municipality of Morón, Province of Buenos Aires) handed over loan by the Municipal Governor of Buenos Aires, brigadier Osvaldo Cacciatore, of the VII Arial Brigade of Morón. Through the testimonies of survivors, it is possible to establish the identities of around fifty people that were detained there illegally, but the fragmentary character of the information implies that there were many more than fifty detainees.

The house was abandoned and blasted with dynamite after the escape of four detainees on the night of March 24th, 1978. The exterior walls stayed standing until 1985, when the Municipal Governor elect of Morón, Norberto García Silva, ordered its complete demolition. From then until the year 2000 the terrain was used as a soccer field within the municipal park “Gorki Grana”, located in the former country house of the Seré family. In 2000, two new spaces within the park were created by means of an agreement between the Municipal Governor Martín Sabbatella, the Seré Association for Memory and Life, and the School of Philosophy and Arts of the University of Buenos Aires. Next to the space where the clandestine detention center used to be located was created a House for Memory and Life, headquarters of the municipal leadership of Human Rights and of the Seré Association for Memory and Life. Also undertaken was the archaeological recuperation of the remains of the mansion with the objective of creating there an Interpretive Center about State terrorism that links the surrounding community with the struggle for memory.
