Vahram built the Church of Surb Astvatsatsin in 1026, fortified the complex with thicker stone walls, and added three bastions along the ridge of the Arkhashen canyon.
Despite being unusual for a military installation, a bath house was built in the same period and has remained moderately intact along with the water supply system.
A covered passageway that led from the fortifications along a steep pathway descending down a cleft in the rocks to the Arkashen River performed such a task.
During the long period from 900-1100, works are carried out to restore Amberd's eastern entrance and fortify all of it, as previously it was only an unfortified summer residence.
The first-born Hovhannes-Smbat receives the crown of Ani, the possession of the Ararat Plain, all the region of Shirak, and Amberd.
From this date onward Amberd becomes the most important center in the defensive system of the Shirak region, and the kingdom of Ani.
1040-1050 - Before the death of Vahram Pahlavouni, Sargis Vardapet visits Grigor Magistros Pahlanuni who is at Amberd on an assignment for the king, Gagik II.
The Byzantine emperor Constantine IX Monomachos calls the king Gagik II and forces him to hand over the city of Ani.
1050 - Katakalon Kekaumenos and General Konstantin take possession of fortresses belonging to Gagik II, which had been captured by the Emir Shaddadiyan, in one of the many Turkish raids.
The fortresses are: Sourb-Mari (Sourmair or Sourmalou), Ampier (Amberd), Sourb Grigor (perhaps near Parpi) and Khelidonion (Tsitsernakaberd).
1064 - The fortress of Amberd is partially destroyed and reconquered together with provinces of Ayrarat, Lori and Syunik by the Seljuk king Alp Arslan, during the fourth invasion of Armenia.

1200 - The heroic liberation of Amberd by Zakare Sipahsalar general of Georgian and Armenian armies is commemorated by a khachkar in the Norashen church at Iraklou.
1215 - One of the most important feudatories, Vache, and father of Prince Kurd Vachutian, buys the fortress of Amberd from Ivane Zakarian.
1254 - The Vachutian princes, well protected by their own defense system, not only succeed in remaining independent during the Mongolian occupation, but carry out an autonomous policy of friendship and allegiances as well.
In 1254 the king of Armenian Cilicia, Hethum, stops at Amberd as guest of Kurd II Vachutian on his way to the court of the Mongolian Khan to sign a pact of alliance with him.
1936 - Excavations are begun with the participation of experts from the Hermitage Museum and the Academy of Sciences of Soviet Armenia, whose director is Joseph Orbeli.
