If you would like to see Yerevan from up high, Victory Park is the place for that. It is where the statue of Mother Armenia is located and which can be seen from many parts in Yerevan. The park is a calm place to have some walks and relax. There is a small human-made pond here too. There are some carousels here, at least one of which is an attraction not only for kids, but also for adults. I remember a friend telling me she once went alone for a ride on the ferris wheel to get rid of her fear of heights.
In this park there are some military items exhibited around the Mother Armenia statue, while inside the statue there is a museum on Armenia’s participation in the Second World War, as well as the war in Artsakh. The victories in these wars gave the name to the park. I haven’t been to this museum though (which is free and open every day apart from Mondays from 10:00 – 17:00 and on weekends from 10:00 – 15:00). Despite the militaristic coloring of the park, one thing I like about it is that current statue, although again militarized, is a woman who replaced Stalin’s statue. The latter stood there until 1962.
I would advise visiting this place at least once for the view.
