This key is used to tag individual defensive structures mainly at historic/pre-modern fortifications. It is intended for all structures that were built for the defence of territories in warfare. This includes fortified settlements as well as forts that are/were uninhabited during peacetime.
Values for defensive_works=* contain terms used in fortification engineering.[1][2][3][4][5]
How to map
Individual defensive works should be mapped as Nodes at their centre, as
Ways along a centre line or as
Areas along the outlines. The best fitting method depends on the size and shape of the structure. They should be tagged with defensive_works=* and may receive additional tags.
Mappers are encouraged to combine this tag with other tags where they are relevant. If a structure is actively used by the military, it is recommended to add a military=* tag to it.

Tags to use in combination
- name=* - if a defensive structure is named. Do not use the name of the fortification to tag individual structures.
- heritage=* - if the structure has a heritage status. If only the entire fortification has a heritage status, do not use heritage tags for individual structures.
- building=bunker - if the structure is a
bunker
- start_date=* - year of completion
- abandoned=yes - if the structure has been abandoned and shows signs of decay
- ruins=yes - if the structure is in ruins
