Akhurian River in the context of Gyumri

Yererouk (Armenian: Երերույքի տաճար, Yereruyk’i tachar), also Yereruyk or Ererouk, is an ancient Armenian church near the village of Anipemza in the Shirak Province of Armenia. Yererouk was built on a plateau near the Akhurian River, which defines the frontier with Turkey, about 5 km southeast of the ancient city of Ani.

The basilica is considered one of the ancient examples of Armenian architecture, belonging to the Paleo-Christian epoch (4th–6th century). It was initially started in the 4th century, then was postponed in the 5th century and finally completed in the 6th century. Because the basilica is not mentioned in any historical sources, the dates are hypothetical. However, the most recent studies have analysed the architectural characteristics with stratigraphic tests, the study of the sculptural decoration and epigraphy, the comparation with similar churches in Syria.

Anipemza (Armenian: Անիպեմզա) is a village in the Ani Municipality of the Shirak Province of Armenia. The Statistical Committee of Armenia reported its population was 523 in 2010, up from 349 at the 2001 census.

Anipemza is located on the closed Armenia–Turkey border on a bank of Akhurian River on which opposite coast there are ruins of the ancient Armenian city of Ani in Turkey. In 7 km to the north from village there is Ry station 'Ani' of Armenian Railway. Anipemza was founded in 4th century by Kamsarakan princes. The village Anipemza is well known for ruins of Yererouk basilica of 4th-5th century. Near to village the industrial complex of building materials (processing of Pumice, Tuff, Andesite) is located.
