Garabaghlar Mausoleum, Mausoleum in Garabaghlar village, Kangarli District, Azerbaijan

The Garabaghlar Mausoleum is a cylindrical tomb tower in Kangarli District, Azerbaijan, its body formed of twelve semicircular facets on a stone pedestal. Inside, the burial vault takes the shape of an equal-ended cross, covered by a groin vault. Two minarets with rectangular foundations stand about 30 meters away, joined by a portal bearing the name Jehan Qutui Khatun.

The complex grew in stages: the two minarets date to the late 12th and early 13th centuries, while the tomb and the small portal joining the minarets were built in the first half of the 14th century, under Abu Sa'id Bahadur Khan. An inscription on the portal names Jehan Qutui Khatun as the patron, possibly the wife of Hulagu Khan. Excavations in 1940 uncovered walls of a building identified as a khanega between the minarets and the tomb.

The Arabic inscription on the portal between the minarets records an order by "Jahan Qutui Khatun", possibly the wife of Hulagu Khan and mother of Tekuder, Sultan Ahmad. The mausoleum's exterior is covered with turquoise tiles forming geometric patterns and bands of the Muslim creed in square Kufic script, repeated many times. The white letters on a blue glazed background made these inscriptions legible from a distance.

The complex stands in Garabaghlar village of Kangarli District, about 30 km from northwestern Nakhchivan, so it is reached by road rather than on foot. The minarets keep narrow spiral stairs of simple tablet bricks, and the upper parts are badly damaged, so climbing is not an option. The interior burial vault takes the form of an equal-ended cross and gets little daylight.

The minarets shift in shape as they rise, starting from octagonal bases and opening into round shafts covered in bricks with a turquoise glaze. This combination of a change in geometry and a colored glaze on the same tower is rare among medieval structures in the South Caucasus.
