In Garzau, in the vicinity of Strausberg, there is a bunker that formerly housed the Organisational and Computer Centre of the National People’s Army. The site is a genuine memorial to the computer technology of the more recent past, now consigned to the status of a museum exhibit. It was here, several metres under the ground, that the heart of an internal GDR precursor of the Internet used to beat. Cabinet-sized computers with enormous magnetic memories were used to collect messages via remote data lines from all units of the National People’s Army. A 170-strong team would prepare the data and forward it on-line to the Ministry of Defence. However, Garzau would only have become really important in the event of war or a crisis, which is the reason why the bunker was designed so as to withstand a medium-sized nuclear weapon explosion even from a distance as close as 1200 metres.
