Korcabulaq or Aghbradzor is a village in the Lachin District of Azerbaijan.
The village was located in the Armenian-occupied territories surrounding Nagorno-Karabakh, coming under the control of ethnic Armenian forces during the First Nagorno-Karabakh War in the early 1990s, subsequently becoming part of the breakaway Republic of Artsakh as part of its Kashatagh Province, where it was known as Aghbradzor (Armenian: Աղբրաձոր). The village was returned to Azerbaijan as part of the 2020 Nagorno-Karabakh ceasefire agreement.
Historical heritage sites in and around the village include a burial mound from the 2nd–1st millennia BCE, a khachkar from 1068, a khachkar from 1069, a khachkar from 1075, an 11th-century khachkar on a pedestal, the 11th/12th-century monastery church of Mayrejri Vank (Armenian: Մայրեջրի վանք), three 11th/12th-century khachkars, an 11th/12th-century defensive wall, the cemetery of Mayrejri Vank from between the 11th and 17th centuries, four 12th/13th-century khachkars, a 12th/13th-century tombstone, a khachkar from 1244, a 13th-century khachkar, a 15th-century khachkar, a 16th/17th-century tombstone, and a tombstone from 1641.[1]
