Argentine architect Esteban Tannenbaum has given new life to one of the most important cultural spaces in Argentina: the CAyC – Centro de Arte y Comunicación, founded fifty years ago by the histrionic Jorge Glusberg and designed by Manteola, Sánchez Gómez, Santos, Solsona and Viñoly. For decades the CAyC has been an interdisciplinary experimental institution focused on the concept of “system art” that until the end of the twentieth century has played a key role in the development of conceptual art in Argentina, in the use of new technologies and in the internationalisation of Latin American art. After its closure the space had changed function and had been heavily altered, with the addition of various subdivisions. Tannenbaum restores the original spatiality, changing only the colour of the interiors, which were originally black. The entrance walkway and spiral staircase remain the distinctive elements of the exhibition space that now takes the name of Walden Gallery.
