Hi. Please use the changeset description field to describe what you changed and why; "updated" is not sufficient. Read more here: https://wiki.openstreetmap.org/wiki/Good_changeset_comments OpenStreetMap is a map for everyone, and has a policy against mapping nonexistent features. Please do not map historical features. See: https://wiki.openstreetmap.org/wiki/Good_practice#Don't_map_historic_events_and_historic_features If you know the dates that something existed, you can instead add it to OpenHistoricalMap: https://www.openhistoricalmap.org/
