Bunker silos are open-sided structures which can be used with vehicles like a loader or tractor to fill and empty them. Bunker silos are common in agriculture for silage. Anyway they can be used for all kind of goods, which can be handled with a loader or tractor. Other usage are for sand, pebbles, gravel, manure, mulch and the like.

How to map

Use man_made=bunker_silo to mark bunker silos.

Map every compartment separately where appropriate. You can tag any walls with barrier=wall.

You might specify the goods stored in a bunker silo with content=*.


  • (Silage-)Heaps, which have been simply heaped on a lawn, should not be mapped as man_made=bunker_silo, because these exist only for some months.
  • Military bunkers or silos should be tagged with military=bunker instead.
  • Three-walled racquetball courts may look similar in aerial imagery but should be tagged leisure=pitch sport=racquet instead.
