 In the case of the Gandzasar and Gtichavank monasteries, the cone over the cupola is umbrella-shaped, a picturesque design that was originally developed by the architects of Armenia's former capital city of Ani, in the tenth century, and subsequently spread to other provinces of the country, including Artsakh.Like all Armenian monasteries, those in Artsakh reveal great geometric rigor in the layout of buildings.In this regard, the thirteenth century's Dadivank, the largest monastic complex in Artsakh and all of Eastern Armenia, located in the northwestern corner of the Mardakert District, is a remarkable case.
