Finally, there are a couple of links currently connected to Ibn Battuta that I don't think are accurate:

Fort Jesus: Fort Jesus was built by the Portuguese in the 16th century, and the nomination package seems to indicate its OUV is based on that construction. Ibn Battuta visited Mombasa in the 14th century.

Old Town of Galle: Galle was founded by the Portuguese in the 16th century, and was not in existence when Ibn Battuta visited Sri Lanka (Ceylon) in the 14th century.

I was looking at a possible new connection to GIAHS. Qanat Irrigated Agricultural Heritage Systems, Kashan was suggested, but my first impression is that this particular qanat system is NOT part of the WHS Persian Qanat system. Am I overlooking something?

See http://www.fao.org/giahs/giahsaroundtheworld/designated-sites/near-east-and-north-afr ica/qanat-irrigated-agricultural-heritage-systems-kashan/en/

And the same for the Subak system of Abian Salak in Karangasem, Bali:

http://www.fao.org/giahs/giahsaroundtheworld/proposed-sites/asia-and-the-pacific/inte grated-agroforestry-system-of-abian-salak/detailed-information/en/

No Qanat system in Kashan is inscribed as part of the "Persian Qanat System" - but other Iranian WHS do contain "qanats" e.g Yazd.
In Kashan the Bagh-e Fin Persian Garden is fed from a qanat.
We have no map of the 4 650 km2 covered by the GIAHS. It may include the Bagh-e Fin but the GIAHS is supposed to be all about "Agricultural systems" and a Persian Palace doesn't really seem to "fit the bill" even if its waters do come from a Qanat included in the area.

For Mines which can be visited underground, Zacatecas' El Eden mine has been suggested. However, does it lie outside of the core zone of the WHS? - Solivagant thought so when submitting the original connection idea.

I had a look at the map provided on the UNESCO website and must say I do not understand what I am looking at.

Yes - it is a mess with its lack of reference points!
First - it is oriented with North to the right!! (see "Compass point" at top right)
If you look at it in that orientation then there is a long "hippodrome" shaped feature with "rounded ends" at the top centre - ie the Western side of Zacatecas. The red boundary line goes just "above" i.e to the western edge of this feature.
If you then look at Google maps for the city centre (correctly oriented N/S) it will be seen that this feature is La Alameda park running SE/NW alongside Av Torrejon. The Cathedral is pretty well central on the UNESCO map - the large rectangle surrounded by streets
It will be seen that El Eden is slightly further NNW than the "Hippodromic" Alameda OUTSIDE the core area. Torrejon continues NW until it circles around Biblioteca Publica with El Eden to its NE. El Eden is situated at the very top of the UNESCO map to the right of the sinuous Paseo Diaz Ordaz which runs along the bottom of the hill - clearly outside the red line area.
With its inscription as early as 1993, the definition of "Historic Centre" for Zacatecas was rather stricter than I suspect it might be nowadays! And it only has the single location .

Thought I would have a look too and yes come to the same conclusion as Solivagant, the mine is one block outside the inscribed area which finishes at la Alameda park.

From the very long list of jonathanfr for the 2023 sites (which I still have not fully finished), I share a few here where I am unsure or more clarification is needed:

Forêts hyrcaniennes
Notable Trees "The oldest trees seen here are 300-400 years old, with some possibly up to 500 years old."
Not that old and individual trees should stand out

Les sites funéraires et mémoriels de la Première Guerre mondiale (Front Ouest)
Art Deco
needs an example

Thanatourist
I am not sure, it needs a quote, These are mostly cemeteries, nothing lugubrious

Hopewell
Extended from original TWHS
More info needed, we don't have it in our site history

Santineketan
Works by Nobel Prize winning authors
need an example of a work of Tagore where Santiniketan is featured

Ancien Jéricho/Tell es-Sultan
Mentioned in the Bible
Sieges and Battles
I think all biblical references to Jericho are from a later date and do not refer to this settlement

Djerba : paysage culturel, témoignage d'un mode d'occupation d'un territoire insulaire
Homeric Locations
Lotus-eaters
I don't think this is relevant, the locations are very limited and much newer

Christ's Resurrection Church
https://www.atlasobscura.com/places/church-of-the-resurrection


Mound City Group National Monument (former tentative list of the United States of America)

And a final one, which leads to a more fundamental discussion of Dependent Territories.

Several of the French sites (Reunion, Martinique) are run as overseas provinces and are not Dependent Territories as per the wiki definition ("a territory that does not possess full political independence or sovereignty as a sovereign state, yet remains politically outside the controlling state's integral area.").

Shall we put these "overseas regions" in a separate connection? (if we have 3)?

We're looking for one in the WWI memorials

I only see "Moundville Archeological Site 1990 1996 ", but that lies somewhere else.

Mémorial de Thiepval

Outermost region
With Portugal and Spain overseas regions
https://fr.wikipedia.org/wiki/R%C3%A9gion_ultrap%C3%A9riph%C3%A9rique

We could use that, but it is EU specific. Maybe we can find one that includes UK and US territories as well, or are these all Dependent Territories?

I emailed you a pdf file with "Mound City Group National Monument" visible.
