For many years, Chartar was the largest and the most improved village of not only Martouni region, but also the Nagorno-Karabakh Republic. After long discussions, a decision was made, as a result of which Chartar became a city again. Once it was a regional center. Chartar was the only regional center having 3 clubs, 5 libraries and 4 schools. In Chartar Alexander Tamanian’s son, Grigor Tamanian designed the project of the Opera House in Yerevan, made of red tufa.
