This oldest monument of Armenian architecture is located near the village of Anipemza, about eight kilometers far from the beautiful ancient city of Ani, which was the capital of the Armenian kingdom from 961 to 1045, although it is now on the other side of the Armenian-Turkish border. The Yereruyk Basilica is still full of many mysteries. For example, there are Greek inscriptions on the south wall of the basilica. During excavations, a large grave, containing seven or eight pedestals, was found and according to archaeologists, these are tombstones. Also, in the territory of the basilica, numerous newborn babies were buried, and the researchers believe that this was connected with some disease.
