The Arshakid Kings Mausoleum and Basilica (Armenian: Արշակունիների դամբարան; also Tomb of the Arshakid Kings or Arshakuni Tomb) is a grave monument complex that sits along a gorge overlooking the Amberd River, and is located in the center of the village of Aghtsk in the Aragatsotn Province of Armenia.

Approximately one hundred meters north of the basilica and tomb complex is a shrine that sits alongside a path leading down to the gorge below, where there are many caves that date from the 16th-18th centuries.

There was however the tomb of King Sanatruk that escaped this looting and destruction due to its enormous, impenetrable and ingeniously built structure.

They came and besieged the secure fortress of Angegh (which is in the Angeghtun district), for at [that place] were the mausoleums of many of the Armenian Arsacid kings, and many treasures had been stored and kept there from [our] ancestors, [g149] from ancient times on.

So they left that place and went on elsewhere raiding, advancing through the Basen areas seeking to come up behind the troops of the king of Armenia.

At that time under general Vassak's disposition were some 60,000 select and martial men who were united in war with one mind and one heart to go and fight for their sons and wives, to give their lives for the land and for the districts of the land they inhabited, to fight for their church, for the oath of worship of their blessed churches, for the oath of faith in the [157] name of their God, and for their native Arsacid lords.

The Sparapet Vassak with 60,000 troops advanced, turning about, [g150] leaving King Arshak in a secure spot somewhere in the Marac' country with attendants.

The bones of the Armenian kings which Vassak retrieved, they buried at the stronghold in the village called Aghtsk, in the Ayrarat district, which is located in one of the narrow crevices of the great Aragats mountain, [in a place] difficult to access..."The mausoleum that had once contained the bones of the Ashakid kings was constructed in the mid-late 4th century.

The low-vaulted chamber is semi-cruciform in plan, with rectangular ossuary niches centered within the structure to the north and south where the royal remains had been placed.

On one (north), the Biblical story of Daniel in the lions' den and a motif of rams is depicted while on the other (south) there are depictions of a mythical hero alongside astrological imagery of birds, a calf amid a grape vine, a cross within a circle with two birds perched on top and a hunter with two dogs striking a wild boar.
