Hellenic Air Force Museum preserves Greek military-aviation history at Dekelia (Tatoi) Air Base north of Athens. Its collection includes aircraft and helicopters, engines, weapons, uniforms, photographs and wreckage connected to the Hellenic Air Force, with restoration and presentation work that has included the Spitfire MJ755. The base setting links the museum to Tatoi’s long aviation history and makes it a distinctive Greek air-force heritage destination. Public visits are permission- and base-controlled rather than ordinary walk-in access; groups and foreign visitors should coordinate with the Hellenic Air Force or its public-relations office before travel and carry the required identity documents. Confirm current opening, escort and accessibility rules with the operator. Address: Dekelia Air Base, 13671, Tatoi, Greece.
