One of the great cities built by Tigran the Great, built in Artsakh (Nagorno Karbakh) was used to 1500 years , but was off limits to Armenians in later times, kept hidden by azerbaijani authorities who want to keep the true history of the region a secret, since they claim it is their land, which is absurd..
You can see the masonry skills of this great Armenian city, compare to those in egypt and babylon, you could not stick a knife through the gaps in the rock, thats how tight they were built.



Artsakh is the ancient name used by Armenians for the Nagorno Karabakh region
