Our goal is the complete representation of all castles and palaces on OpenStreetMap (OSM) and Wikipedia (WP)!
On Saturday, April 27, 2019, a working meeting of both communities (and other interested parties) took place at [:de:Schloss Lenzburg|Schloss Lenzburg]] to coordinate the different works and to bring the different projects and subprojects closer together.
Another meeting is planned for 2020.
