Amid questions, reflections, and debates, the work of Clorindo Testa embodies an innate connection between artistic and architectural experimentation, reflected in many of his built projects, sketches, models, and plans. From the Mariano Moreno National Library to the former Bank of London building in Buenos Aires, his production is of such scope, diversity, and complexity that it constitutes a major source of study, one that also includes unbuilt projects that deserve visibility and recognition on a global scale. In his final years of professional activity, two unbuilt projects of religious architecture highlight Testa’s work not only as an architect but also as a visual artist.
