The more structural issues we had in not being able to categorize some of the TWHS:
elsslots:
Structural
Recent Archeology ones
La Cité Historique de Hamdallahi - it is archaeology in a sense, but of the most recent kind, so maybe Relict? Or just straight Civilizations of Sub-Saharan Africa
Ciudad Vieja / La Bermuda -  Archeo sites post-Columbian? Similar issue to what we had with Archeo medieval Europe – these are just of a later date but still archeological remains.Â
Sites of Great Moravia - Â it's an Archeological site of Medieval Europe, but we don't have a category for this. The most similar site I can think of is Bolgar. We have this as Urban landscape - Medieval European, which doesn't feel right either.
Geological ones
Baltic Klint - Baltic Klint is about the Geology and Stratigraphy of the Klint - not its Marine/Coastal location or anything about the ecosystem of that location. Needs a category like Earth History
La Brea Pitch Lake - another "Geological/Geomorphological site for which we don't have an adequate category
Abu Dhabi Sabkha - This site is about Geology/Geomorphology and not about an ecosystem. IMO we don't have a suitable Category for it
Les Alpes de la Méditerranée (Monaco + France) - (For Italy we said Mountain Marine & Coastal. For Monaco we put it aside. It is really "geological"
Pilgrimage roads
Darb Zubayda - "NOTE 1 These 3 ""Pilgrimage Roads"" have almost exactly cloned descriptions on the UNESCO Web site inclusing the same suggested criteria AND the same ""Comparison"" sites. They are described as comprising - ""Stations and Forts""...""Pools, canals and wells, and water reservoirs... along the route through the desert.... in use from the pre-Islamic period to ....the 13th century CE"".
The Comparators suggested include
The Negev Incense Rte (Which we have as a Relict CL – though the AB eval calls it a ""Fossilised CL"").
The Kii Mountain pilgrimage route (Which we have as ""CL Assoc"")
The Spanish Rte of Sant de Compost (Which we have as a Religious Structure)
Silk Roads (Which we have as ""Transport & Trade"").
All 3 ""roads"" justify the same answer – but which? CL Relict or ""Transport & Trade""? I don't know!"
Syrian Hajj Road -
Egyptian Hajj Road -
Modern architecture
Alvaro Siza's Architecture Works - "His work in Portugal includes various building types: individual houses and entire residential areas, churches, restaurants and public buildings such as schools, universities and libraries." How to choose or what else?
-> we have this one left as an isolated case, but the issue also occurs at other modern architecture sites
