The echoes of the bells from the Church of San Ignacio of Loyola, in Buenos Aires, resound on the stones of the old Manzana de las Luces historical complex, one of the last buildings from the colonial era that survive in the city’s historic center. The place, which through the centuries has been a convent, a Museum of Natural Sciences and even a Faculty, transpires hispanic barroqueness. It is now a museum without a permanent exhibition; it is, in its way, a monument of its own. In the courtyard, the spectator looks upwards and there stand the balconies of the old cloisters, higher up the glass and steel walls of the skyscrapers of the financial district and, poised on the museum’s ceiling, observing this ancient patio, an unwinged angel that looks out of place. And it is. Or maybe not.
