A citywall is a fortification used to defend a city or settlement from potential aggressors. In ancient to modern times, they were used to enclose settlements. Note that barrier=city_wall also exists.

Walls that are still standing and in good shape probably qualify for both barrier=city_wall and historic=, in that case historic=* is obvious as all city walls are nowadays historic.

Note that existing city walls that are ruined, maybe with only foundations remaining may no longer qualify as barrier=city_wall but are still historic=.

How to map

Draw a way way along the citywall.
