Hellenic Cosmos, the cultural centre of the Foundation of the Hellenic World (FHW), at 254 Pireos street, is one of the most perfect museum areas of Athens. It lies on a former industrial zone in an area of approximately 60,000m2, on an axis between Athens and Piraeus, where memory of Athens past meets the city's modern identity. It is an ultra modern, living museum of Hellenism, across the sciences, arts and every aspect of society: it aims to be a source of information that satisfies the needs of contemporary "society of knowledge".

Part of the Foundation's work is presented at Hellenic Cosmos, while another part is available on the Internet. Interactive exhibitions, educational programmes, Virtual Reality tours and documentaries, which combine excellent historic information with the state-of-the-art technological applications, familiarize visitors with Hellenic history and culture in their development through time. Furthermore, the Cyber Hall provides access to the Foundation's history sites and CD-ROMs.

The Cultural Centre initial area occupied 16,000m2 but continuously expands with new facilities: in December 2006 the "Tholos" was inaugurated, with a capacity of 132 people, which houses the most perfect, presently, Virtual Reality system and on March 21st 2008 the "Theatron" opened its gates, a building for various uses that will host plays, music concerts, dance performances, conferences, exhibitions and other events (fashion shows, speeches).
