GeoJSON
Use Overpass to create a draft GeoJSON (e.g., at Data:Sandbox/Betterkeks/xxx.map), and eventually expose (e.g., Data:Hannover/Roter_Faden.map), encased into Map Data by the below to which styling is then added for mapframe, and recorded in Wikidata as geoshape‪; see.

{  "license": "ODbL-1.0",

"zoom": 14, "latitude": 52.371993, "longitude": 9.7354699,

"data": { "type": "FeatureCollection", "features": [ // Replace this with the // GeoJSON, augmented with // the below. ]   } }

To style, add the below into "properties". "name": "City Wall", "stroke": "#8E5913", "stroke-width": 1, "stroke-opacity": 0.7, "fill": "#CCB56C", "fill-opacity": 0.4

Also add the following immediately below "properties". "id": "myCityWall",

Alternatively, draw features in JOSM, possibly by hand-tracing from images such as the below transformed into a JOSM overlay using satellite imagery for reference, and handcrafting your exported GeoJSON into a map file (you may need to add a name and id). Even if the image is in the public domain, when using JOSM you may need to apply at least the ODbL-1.0 license. Make every reasonable effort to acknowledge the owners of copyright material, and be pleased to hear from any copyright owner who has been omitted or incorrectly acknowledged so you can correct.
