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.

Armenian architecture comprises architectural works with an aesthetic or historical connection to the Armenian people. It is difficult to situate this architectural style within precise geographical or chronological limits, but many of its monuments were created in the regions of historical Armenia, the Armenian Highlands. The greatest achievement of Armenian architecture is generally agreed to be its medieval churches and seventh century churches, though there are different opinions precisely in which respects.
