The Mausoleum of Kara Koyunlu emirs (Armenian: Կարա-Կոյունլուների դամբարան) is a 15th-century mausoleum located in the village of Argavand, Ararat Province, on the outskirts of the Armenian capital Yerevan. It was erected in 1413 by a local ruler, Pir Husayn, most likely over the grave of his father Saad, during the rule of the Qara Qoyunlu, a Turkoman dynasty which ruled over Armenia, most of Iran, and other lands in the 15th century. The site is thought to have served as the dynastic cemetery of Emir Saad or his successors.
