I definitely agree with a lot of your points, and it’s clearly poorly maintained.
It’s not much better from other angles. And if you thought the outside is bad, try the hallways…
All I can say is that it is a metro entrance so it’s more like a transition space on people’s commutes. Maybe the architect intended people to hurry the hell up and get to work rather than loiter in the park, haha.
Looking at it’s history, it was constructed during a period when Armenia was a part of the USSR and metro project funding was limited to cities with populations over 1mil. Despite not meeting that requirement they continued anyways and it took them almost a decade to build the entire metro. I think the result reflects the struggle of the city over the last half century.
Even today, despite having 15mil annual ridership, expansion construction has been frozen since the 90’s. They did manage to update/renovate the metro system in 2012 but only after receiving funding from the European Union.
