The construction of the establishment begun in 1955 and was completed in 1972. It was originally designed to be the Headquarters and Coordination Center of the Hellenic Navy General Staff. Facilities for servicing NATO needs where added to the project later on.

From 1983 to 1997, the broadening of the tunnel, the reconstruction of its parts and the modernization of the telecommunication systems and the electrical engineering equipment carried out.

Various projects of enhancement and modernization have been taking place since 1997 up today.

The construction fulfills all the standards of confronting a nuclear or biochemical war as required at that time because of the Cold War and is divided in three parts: The Structural part, The Electrical Engineering Part and The Telecommunications part.


The mission of Hellenic Maritime Communication Headquarters is to ensure the efficient operation of the communications systems and to support the Command and Control systems in order to contribute to the efficiency of the Command and the Operational Control of the Units and the Services of the Hellenic Navy.

It provides the necessary infrastructure and means so the Fleet Headquarters (FH) meets its oligations.

The underground facilities consist of a complex of tunnels which include the areas where the telecommunication systems that cover both the needs of the Hellenic Navy and NATO, are fully operational. Further more, the underground facilities also include the electric, engineering systems and the AC systems, as well as areas of Operational concern (Dining room, Staff area etc)
