Hi oloi :)

I'm one of the OpenStreetMap volunteers. You were right about the castle :) It has been mapped twice, both as a node and as a relation:
https://www.openstreetmap.org/relation/3734604
https://www.openstreetmap.org/node/8921556784

They have slightly different tags, so you could transfer any tags from the node to the relation and then close the note :) If you need any help, let me know. Or you could send a message to the Greek forum https://forum.openstreetmap.org/viewforum.php?id=27

Thanks for improving the data and happy mapping! :)
