 Bunker silos are unroofed structures with at least one open side, which can be used with vehicles like a loader or tractor to fill and empty them. Bunker silos are common in agriculture for  silage. 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, other landscaping materials, manure, mulch, and the like.

How to map

Draw the outline and add


  • (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.
