I have just finished going through all Russia TWHS for the TWHS project. Here are some findings:
· The list of 27 is not as great as it could have been. It has 2 renominations for technical reasons (boundary modifications), the TWHS of Shulgan-Tash is also covered by the TWHS of Bashkir Ural and the best part of the Treasures of the Pazyryk Culture TWHS (with horse & human burials in permafrost) is already technically inscribed as part of the Golden Mountains of Altai WHS.
· There are more Golden Ring sites, one must be a specialist in the history of Russian Architecture to enjoy those.
· There's quite a lot of rock art. Petroglyphs of Lake Onega and the White Sea seems the most exceptional in terms of numbers, themes and purity.
· There are a lot of flowery titles - The Great Vasyugan Mire turned out to be an enormous peat bog (and not a Russian-Orthdox cathedral spire).
· A lot of the descriptions seem to be written by and towards scientists (and translated directly into English). Which often makes it difficult to grasp what the OUV is. Ilmensky mountains is one of those – known for its mineral variety it could be interesting enough.
· There's even a Greek ancient city (Tanais) on it!
· The Russian colonization of the East could have a WHS: choice is between Yeniseysk and Irkutsk.
· I liked the Chukotka Arctic Marine Hunters Heritage (a real frontier site between Russia and the USA, and a cultural site from the far north of which we do not have many), Divnogorye seems like quite a spectacle, there's the group of Soviet WWII memorials around 'The Motherland Calls!' and possibly the Jeyrakh-Assa Reservation in Ingushetia (Vainakh towers, similar to Upper Svaneti in Georgia).
