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.

The Garni Temple is the only standing Greco-Roman colonnaded building in Armenia. Built in the Ionic order, it is located in the village of Garni, in central Armenia, around 30 km (19 mi) east of Yerevan. It is the best-known structure and symbol of pre-Christian Armenia. It has been described as the "easternmost building of the Graeco-Roman world" and the only extant Greco-Roman temple in the former Soviet Union.
