Vankasar church, Medieval church in Aghdam District, Azerbaijan.

Vankasar church is a stone structure perched on a hilltop in Aghdam District with a central dome and three altar apses that remain visible for several kilometers across the surrounding plain. The building displays the geometric layout and solid masonry typical of medieval religious construction.

The structure dates to the 7th century and received its first documented mention in 1858 when Archbishop Sargis Jalalyants recorded it as monastery ruins. The site experienced periods of use and abandonment across the medieval and later centuries.

The church is known in Armenian as Vankasar and in Azerbaijani as Beşikdağ kilsəsi. Local tradition recorded by Makar Barkhudaryan attributes its construction to Prince Vache II. In the 1980s restoration, Armenian inscriptions and carvings were destroyed and khachkars moved or damaged.

The site is located at coordinates 40.0721°N and 46.8874°E and requires a trek over hilly terrain starting from the nearby village of Shahbulagh. Visitors should prepare for uneven paths and variable weather conditions typical of highland areas.

In the 1980s, restoration by the Azerbaijani government destroyed Armenian inscriptions and carvings and moved or damaged khachkars. A 2024 Instagram video showed that the cross atop the dome had been removed.
