In the summer of 2019, Armenian and German researchers discovered an amazing thing with their spades: huge slabs of Roman concrete were discovered at a depth of 30 centimeters from the surface of the Ararat Valley. It is assumed that these slabs were hundreds of foundations of the aqueduct, an unfinished Roman pipeline designed to deliver water to the ancient city of Artashat. Although the original source of the aqueduct is not exactly known, however, according to calculations, its length was about 31 kilometers, and perhaps it began at the temple of Garni. 

We want to recall the fact that Rome controlled the ancient capital of Armenia Artashat for only three years, then the Romans retreated to the West. The construction of the aqueduct remained unfinished, and all traces of it eventually disappeared for centuries, remaining under a layer of earth and dust.
