Hello!
We have been doing a hard work adding all the monuments listed by the Basque Government and lot of protected buildings and monuments in Navarre, and it would be great to have them uploaded into the database.
All basque monuments are identified with the item Q65553409 (https://www.wikidata.org/wiki/Q65553409)
Uploaded items in Navarre (list is unfinished) are subclasses of Q66087642 (https://www.wikidata.org/wiki/Q66087642). This list will be updated, as we have to check every municipality by hand (no central accessible repository yet).
Thanks!
