I’ve been looking at tumuli the last couple of days. In Ireland, they’re usually called barrows, but according to Wikipedia, it’s the same. So I went and tidied tagging in some of the features tagged as barrows (mostly site_type=ring-barrow/round_barrow and archaeological_site=ring-barrow/round_barrow etc).

I’ve also added that very important information to the wiki and created a table of the most commonly used tags related to tumuli/ barrows.

I noticed some possible duplicates in the tagging: I would think that round_barrow and round_tomb are the same, for example. Some of the tumuli tagged as mound probably fall into that category as well.

This morning, I started drawing some of the types and uploading them to WikiCommons (all as CC0), mostly after photographs I found online, because there didn’t seem to be any diagrams of the different types on WikiCommons. Most of them are just rough schematics (I say rough, it took me forever to draw every single stone), but one is actually a specific keyhole tomb in Algeria (there are hundreds mapped in Algeria!):

Keyhole tomb in Algeria

When you look at keyhole tombs, they actually reminded me of that one Pokemon that you find in a cave at the end of the RBG edition, I think. I can’t remember the name. Uknown, no wonder I couldn’t remember it.

In the Sahara Desert, they seem to be the only thing mapped for kilometers on end. Makes sense, though, if there’s nothing else around. Antenna tomb

It was another very interesting and educating exercise anyway. And maybe the table will help other mappers.
