Historical geography

A dated anchor, not an exact border

The local map uses modern coastlines only for orientation. The marker identifies this record's geographic anchor, not the full reach of a community or polity.

Map geometry loads only when requested. Modern outlines are orientation only; historical geography and identities changed through time.
