In this episode of On Art, we take a closer look at Delhi's Pragati Maidan, where the landmark Hall of Nations and Hall of Industries were demolished. We visit the history of these legendary buildings and let you know what will come in their space. After that, we get to know about Tracing Art in Public, a new publication about public art which launched with an evolving art installation in Delhi's Govindpuri neighborhood. Also on the show, we visit a festival celebrating the art of the Northeast.
