The Armenian Church plays an important role World Heritage properties

Currently, three properties in Armenia are inscribed on the World Heritage List: Monastery of Geghard and the Upper Azat Valley (2000), Monasteries of Haghpat and Sanahin (1996), Cathedral and Churches of Echmiatsin and the Archaeological Site of Zvartnots (2000). 

The Armenian Church, owner of all World Heritage properties in Armenia, plays an important role in the management of the World Heritage properties.. 

The monastery of Geghard contains a number of churches and tombs, most of them cut into the rock, which illustrate the very peak of Armenian medieval architecture. The complex of medieval buildings is set into a landscape of great natural beauty, surrounded by towering cliffs at the entrance to the Azat Valley. 

The Monastery of Geghard, with its remarkable rock-cut churches and tombs, is still preserved in its natural setting. The authenticity of the group is high, not least because the property has been in continuous use as a monastery for many centuries. All constructions included in the property, as well as the landscape, are not threatened in spite of restorations carried out during course of time. To meet conservation challenges, scientific research, renovation, fortification, design and preventive measures have been undertaken in order to ensure that authenticity is retained. Due to the passage of time, a part of the wall adjacent to the auxiliary construction collapsed and was renovated in 2006-2007, keeping the original materials. The designs for water isolation of the rock-hewn part and comprehensive interventions for Geghard Monastery were drafted in order to strengthen the complex.

Monasteries of Haghpat and Sanahin are two monastic complexes that represent the highest flowering of Armenian religious architecture, whose unique style developed from a blending of elements of Byzantine ecclesiastical architecture and the traditional vernacular architecture of the Caucasian region. 

The churches at Echmiatsin and the archaeological site of Zvartnots vividly depict both the spirituality and the innovatory artistic achievement of the Armenian Church from its foundation.
