One of the world's oldest continuously inhabited cities (founded 782 BCE as Erebuni fortress by the Urartu king Argishti I — older than Rome) and the "Pink City" (built in rose-coloured volcanic tuff) where the Armenian Genocide Memorial (Tsitsernakaberd, 1967: the eternal flame and 12 basalt slabs for 1.5 million dead) and the Matenadaran (23,000 manuscripts including the 405 CE Armenian alphabet creation by Mesrop Mashtots, the most precisely dated alphabet creation in history) stand 3 km apart, and where Mount Ararat — the snow-capped national symbol visible across the Ararat plain from 120 days per year — is in Turkey since the 1921 Treaty of Kars.
