There is no doubt that Nirayama is recognised as "a" place to go to view Fuji - "Nirayama sees many visitors from bigger cities (such as Tokyo) coming for seasonal picking and the picturesque views of Mount Fuji." (wiki)
Yesterday I "did" a Google Street Map "tour" of the Furnace area and there seems to me no way that one can see Fuji from inside the core area. This is quite limited and the photo provided in the link will be outside it I believe up a hillside. The core area is surrounded by trees and buildings
Have a "go" yourself!!!

http://www.ringbell.co.uk/info/hdist.htmI think we can assume that Saloum is at or hardly above sea level.
If we assume that Fort Bullen is 14m above sea level and that the viewer is another 1.7m higher still - then the maximum distance which could be seen purely on the basis of the curvature of the Earth is 14.7kms. Google Maps puts the straight line distance between Fort Bullen and the tip of Saloum at 12.3kms. I would think that the other way round might be better - ie. making out Fort Bullen from Saloum. But in all honesty I don't think either is likely in the humid atmosphere of Banjul/Saloum. We have already tried to make the "Rules" for this Connection reflect "real possibilities" (I made the original suggestion and "rules" for this "Connection" having been to Tenerife and realising the possibility) - perhaps we need to extend them to cover for "Normal viewing conditions." I.e not a "once in a year" clear day using a Swarovski telescope and managing to see the flag flying at the top of the pole!!! Also exclude abnormal atmospheric conditions, reflection, refraction etc - "interesting" though they may be as phenomena!
Re Tallin From SuomenlinnaI don't know if people remember back in 2013 we had a discussion on whether it was possible to "see" Mt Etna (then erupting) from Malta 200kms away!!!
https://www.worldheritagesite.org/forums/index.php?action=vthread&forum=8&topic=1775 The accompanying links mention the effects of Refraction. The above calculator arrives at a distance of 206.7kms as the furthest distance where someone at see level could see the very top of a mountain 3350m high. I think also in the case of eruptions etc there will be "reflection" down from clouds/atmospheric dust etc. In the case of Tallin I suspect that what people on Suomenlinna are seeing is the reflection of Talinn's lights. The Google distance from Talinn t to Suomenlinna is c79 kms. Pikk Hermann (the highest tower in Talinn) is 45.6m. Even allowing for being on Suomenlinna at say 27m (the height of the Church tower that is a max distance of 27 + 45.6 m = 72.6m. A max distance to see of 30.4 kms. There seems no way that a direct image of ether place from the other is possible.
I have asked our guide from Iran about
Maidan Emam from Chetel SotounChetel Sotoun from Maidan Emam (specifically from the Ali Qapu)
Maidan Emam from Masjed-e Jame (available to tourists rather than Muezzins!!).
Juha Sjoeblom says he has photos which show Chetel Sotoun from Ali Qapu. It would be very helpful if he would send one to Els!!! I have checked my photos but none of them show it. But that may because I didn't take any looking "round the corner" AWAY from the Maidan and behind the Ali Qapu. Another possibility which occurs to me from remembering our visit is that the stairs to climb the Ali Qapu might have had windows at the rear of the palace which allowed views in the direction of Chetel Sotoun.
I supsect that the answer to the other 2 is negative. The Chetel Sotoun is surrounded by lush trees and all my photos would indicate that there is no real view outside it from inside.
Tower of London/Westminster: from each other or GreenwichThere is no reason to think that any of these is possible. As meltwaterfalls says - the Tower of London in particular is rather small particularly in relation to what has been built around it - much to the chagrin of ICOMOS!! The Thames does a lot of twisting as well so there is a lot of "London" in between any 2 places along it!
Nevertheless Els's raising of this issue HAS identified some additional connected sites which we had missed!
