Cooperation between OTE and ELTA employees / 1971

The tangle of the Museum's history begins to unravel in early 1971, when a group of employees of OTE and the Hellenic Post (ELTA) was formed to examine the possibility of establishing a "Museum of Telecommunications and Postal Systems". In October of the same year, the members of the group submitted to the management of OTE a comprehensive proposal with tables of exhibits, various OTE objects of museum character and proposals for the location and organisation of the Museum.

The proposal received a positive response from the Management and the proposed objects were bound and stored to become the first exhibits of the Museum, while the plans of the OTE Administrative Building under construction in Maroussi provided for an area of 800m², on the ground floor of the building, with the designation "Museum".

"Telecommunications Museum" / 1979

In the following years there would be no substantial development on the issue of the Museum, until in 1979 the Research Directorate of the General Directorate of Development submitted a comprehensive proposal for the establishment of a "Telecommunications Museum". To the already existing exhibits it was proposed to add new ones, which would "highlight the technological development of telecommunications", while for the location of the Museum, instead of the original 800m² space, which was no longer available, it was proposed to create a 1,000m² building on the land of the Administrative Building. In order to ensure the proper functioning of the Museum, the Directorate of Research recommended that the Museum should be organised as a "service function of an appropriate level with its own budget and placed under the Directorate of Education".

"Museum of Telecommunication Systems" / 1987

There follows a period of exchange of notes between the various services, where each transfers to the other the responsibility for the planning of activities related to the establishment of the Museum. A pivotal year in the history of the Museum was 1987, when Stylianos Polycrates, Deputy Director of the Sub-Directorate for the Maintenance of Radio Systems, in a recommendation to the Board of Directors of OTE on 1 April, requested the establishment of a "Museum of Telecommunications Systems". Since 1984, he himself had created an "Instrument Showroom" in the building of the Maintenance Sub-Directorate, at 3 Fokionos Negri Street, consisting of old equipment from various departments of OTE.

On 28 April 1987, the Board of Directors of OTE decided to create a Museum of Telecommunications Systems Materials, granting a section of the second floor of the Nea Kifissia building for the "temporary" housing of the Museum. In 1990 the Museum was inaugurated and 20 years of efforts became a reality.
