With your criterion cities on mountainous regions have a bit of unfair advantage. Another Armenian city https://en.wikipedia.org/wiki/Van,_Turkey https://en.wikipedia.org/wiki/Van,_Turkey, which is older than Yerevan, would match it too, but it's not included in the list on wikipedia. (Maybe because a large part of Van have been ruined and left uninhabited in ~1920s).
