A pleasant place to walk. There is a wonderful view of the city. The walls of the old fortress, along which you can walk, admiring Yerevan and the surrounding area. A small museum, just the kind to not get too tired. But informative enough! I learned for myself about the system of an ancient water pipeline 80 km long, which in very old centuries stretched up this mountain, into the fortress. And there are many other interesting things about winemaking, for example, that some ancient grape varieties are still used. Be sure to climb this fortress if you are a romantic!
