OK, thanks. I put a comment in the other changeset: changeset/7850338

Is the Monemvasia lighthouse really disused? I am asking because there are two seemingly duplicate points with many details on the same lighthouse. I would eventually mark the building itself as the lighthouse as the beacon is located on top of the building. Then I could copy the metadata from the duplicate points and delete them afterwards. (See also comments in changeset/33268593)

Concerning the lighthouse in Monemvasia: Is there a special reason, why all the seamark metadata is added to a separate point in OSM instead of the building polygon itself plus a man_made=lighthouse tag? Secondly do you have any information whether the disused=yes is correct? Probably one should also remove the duplicate beacon point?
