The most famous monument of early Christian Armenia is Yereruyk three-nave basilica.
Yereruyk is three-nave basilica church, constructed in 5th century AD. In its architecture three styles are joint. The main nave is constructed in Syrian early Christian style. The main nave's west facade is very beautiful, where the high wall is covered harmoniously with the three different windows of the entrance. From the north and west two small naves with columns are constructed, which reminds halls with columns of Hellenic architecture. The main nave rises from the other naves and arch shaped window of the corners give to the church Armenian breath.
The church is constructed on the six staired stylobata. Near the church was excavated antique water tunnel of 200m length.
All these are harmonized by Akhuryan river canyon and by the silence of surrounding mountains.
