The medieval complex Khalidzor is a fortress reconstruction, which was carried out in the first half of the 17th century and is also known as Khalidzor Pystyn. The fortress gained fame at the beginning of the XVIII century, when due to its impregnable place it became the main fortress of the liberation movement of the Armenian commander David Beck and the center of the liberated region. In 1723, David Beck rebuilt the fortress and, together with his 300 soldiers, resisted the besieged fortress of the 70,000 Turkish army.
In the eastern part of the fortress complex Khalidzor there is also a church. Its architecture is extremely restrained. The builders turned to the old masonry technique of rough-hewn stone. Both the fortress and the main church of the complex — St. Minas , and adjacent buildings are built using the same local technique.
