List of disappearing gun installations (original) (raw)

This is a list of disappearing gun installations. These are artillery installed behind fortification walls with mechanisms that lift the gun for firing and then retract it to protection. These were installed, especially in coastal defenses, from the 1860s until as late as 1923, and were in service as late as the beginning of World War II. Guns in retractable turrets within the Maginot Line and the Atlantic Wall that are sometimes termed "disappearing guns", are not included. The locations of some still-existing installations may be seen in linked OSM or Google maps.
