Document wartime shelters, civil-defence bunkers, underground refuges, and concrete pillboxes.

What you would map
Air-raid shelters, bunkers, and pillboxes communities pin real-world places on a shared map so people can find, photograph, and catalogue them together.
Geography is up to you: a single city, a whole country, or a worldwide atlas.
- Air-raid shelter
- Bunker
- Pillbox
- Other civil defence
What to record on each pin
Each entry should help the next person find the place again and understand why it belongs here.
- Accurate coordinates (stand at the spot when pinning, where safe and lawful)
- Clear photos that show the subject and its setting
- A short, searchable title
- Structure type: shelter, bunker, pillbox, or other
- Pillbox design type if known
- Never enter unsafe or sealed structures; photograph from public land
Why a shared atlas helps
Wartime concrete is widespread and under-recorded. A shared atlas helps enthusiasts compare types and locations safely.
Spreadsheets and private photo albums do not compound. A public community map grows with every contribution and becomes findable on SpotterAtlas and search engines.
