The cathedral was extensively restored in the aftermath of the War and reconsecrated in 1998. A landmark of Shusha and Karabakh and a listed cultural and historical monument of the Artsakh Republic, it has become an icon for the Karabakh Armenian cause. Standing 35 metres (115 ft) high, Ghazanchetsots is one of the largest Armenian churches in the world.
