This property is used on place=city/town (and other place=* of type settlement) to tag the  capital of a country or administrative divisions within countries.

How to map

Capitals not tagged as city or town

Not all country capitals fit into the definition of place=city/town because of size or of definition. Please join discussion on Talk page about tagging.

The following Overpass API query (link) gets all admin_level=4 admin_centres of Germany. The country and admin_level can be adjusted.

out meta;

As of 2016 the admin_centre role can't be used in databases created by osm2pgsql: We do not have this information in the database. osm2pgsql does not have membership information and nodes as relation members do not make it into geometries.
