The brainchild of Greek art curator Helena Papadoupoulos (formerly of New York and Berlin and thus a familiar face on the art circuit), Radio Athènes is an arts nonprofit that advances visual culture. That means it not only mounts provocative and often political exhibitions, but also and, maybe more importantly, hosts deep talks and discourse on cultural issues of our day. Its space is also a bookstore-library. Check the rich schedule of talks and events at radioathenes.org.
