The phrase "we are our mountains" refers most notably to a famous Armenian monument called "[Մենք ենք մեր լեռները](javascript:void(0))," located north of Stepanakert in the Nagorno-Karabakh region. The sculpture represents an old man and woman symbolizing the mountain people of Karabakh and is a key symbol of Armenian heritage and identity in that region.

Additionally, "[Մենք ենք մեր լեռները](javascript:void(0))" is also the title of a 1969 Armenian comedy-drama film directed by Henrik Malyan, which shares the cultural significance implied by the phrase.

Thus, the phrase conveys deep cultural and national identity linked to the Armenian people and their connection to their mountainous homeland. It symbolizes self-identity, heritage, and rootedness in the land.
