Zvartnots Cathedral is a medieval Armenian cathedral near Vagharshapat (Ejmiatsin), Armenia.
Built in the seventh century and now lying in ruins, Zvartnots was noted for its circular exterior structure, unique in medieval Armenian architecture, and a set of interior piers that upheld a multifloor structure crowned with a dome.
Some sources claim that the Zvartnots cathedral is depicted upon Mount Ararat in a relief on Sainte-Chapelle in Paris. However, this is not very likely, as the fresco was painted more than 300 years after the destruction of the church.
Zvartnots was added to the UNESCO World Heritage list in 2000 together with churches in Vagharshapat (Etchmiadzin).
