Hi again. It might be a good idea to go over this changeset. I picked out 2 changes. One because it rang a bell. I taught I came by the word in the wiki and one because of a weird, at least to me, name.

The first one is https://www.openstreetmap.org/node/2168561999 With the name Cenotaph. If it is what the name says then it should probably be tagged "    historic=memorial + memorial=cenotaph". See https://wiki.openstreetmap.org/wiki/Tag:memorial%3Dcenotaph

And the other one is https://www.openstreetmap.org/edit?node=6030845583 (name=The phone booth The Phone Booth". To me it looks to small to be a monument in the OSM meaning. it is on an islet next to a tree. And it also has the tag "tourism=artwork". It might still be some kind of memorial but I can not identify that with the information available.

P.S. The description of monument at the landmark key https://wiki.openstreetmap.org/wiki/Key:landmark is quite different from the one with the historic key :(
