During the 1950s a network of aircraft observation post was built in The Netherlands, as a detection/observation system against low-flying hostile aircraft during the Cold War. Preferably, these were placed on highrise buildings. 134 of these 276 observation posts were built on existing buildings, on factories, mills, water towers, monasteries, government buildings and bunkers. Since their decommissioning in 1964-1968, many posts have been demolished. Approximately 37 posts on existing buildings remain, but mostly go unnoticed and many risk demolition in the future. These remaining aircraft observation posts are remarkable relics of our military heritage from the Cold War.
