The Centre is located in Tallinn, Estonia, on the premises of the Estonian Staff and Signals Battalion. The building itself was built by the Tsarist military in 1905 as a barracks, but it has now been completely renovated, and blends cutting-edge technological solutions within its beautiful, historic walls. While it has hosted many different military institutions over the years, all of them have shared a common bond in the domain of communications. As the technology of communications has evolved, so has the nature of the work and the qualifications of the personnel in the building: NATO CCD COE now hosts one of the most advanced cyber defence research centres in the world.
