History | For more than 35 years we have been leading in the fields of exhibition planning, design, culture, tourism, environment, communication and creative industry.

A course of search, success and reorganisation, which had begun in 1984, ended in 1999 with the foundation of TETRAGON. Since then, we have been constantly evolving and developing, not only increasing, enlarging and expanding our projects and activities on a nationwide and international scale, but also investing in human resources and know-how, in strategic synergies and relationships of trust with many important public and private bodies, in modern equipment, facilities, infrastructure and quality assurance systems.

People | About 50 professionals with high training, know-how and experience, from various scientific and technical fields, collaborate to achieve the best result for each of our projects.

Creators and leaders of TETRAGON are the architects Eleni Vretzaki, Giotis Ioannidis and Ilias Papadopoulos. The company's departments are staffed by architects, museologists-museographers, designers, graphic artists, programmers, computer engineers, historians, archaeologists, philologists, translators, decorators, audiovisual content producers, as well as administrative and technical staff.

Networking | We participate in scientific, cultural, sectoral and business networks and ecosystems, with the aim of both exchanging research and knowledge as well as strengthening our extroversion and competitiveness.

We are members of the global network of OCTANORM (OCTANORM SERVICE PARTNER INTERNATIONAL-OSPI), the European Network of Science Centres and Museums ECSITE, the Hellenic German Chamber of Commerce and Industry, the Technopolis Artificial Intelligence Cluster and the CHORUS Cluster. We repeatedly participate in Greek and international conferences with presentations and announcements, we publish in recognised magazines, we take part in competitions and in research groups, while we are actively involved in the activities of the International Council of Museums (ICOM).
