Artaxata

Artashat, Hellenized as Artaxata and Artaxiasata, was a major city and commercial center of ancient Armenia which served as the capital of the Kingdom of Armenia from its founding in 176 BC to 120 AD, with some interruptions. It was founded during reign of King Artaxias I, the founder of the Artaxiad dynasty. Its ruins are located in the Ararat Province of modern-day Armenia, on the left bank of the Araks River, at the site of the monastery of Khor Virap. It was destroyed and rebuilt several times from the 1st to the 5th centuries AD, before finally being abandoned.

The remains of the great walls of the city and some of its buildings are still visible today.
