[Abarqūh]
Iranian town in northern Fars province. A prosperous centre in medieval times, by the 10th century it was fortified with a citadel and had a congregational mosque. The octagonal tower of mortared stone known as the Gunbad-i ‛Ali was erected, according to its inscription, by a Daylamite prince in 1056–7 to contain the remains of his parents. The Masjid-i Birun, a mosque to the south of the town, may be slightly earlier, although it has many later additions. The congregational mosque (rest.), with four iwans around a rectangular court, dates mostly to the 14th century, although the base of the dome chamber probably belongs to the 12th-century mosque. The many mihrabs within the mosque include a particularly fine stucco example (1338). There are also several mud-brick tombs in the town. These square structures have plain exteriors and plastered and painted interiors. One of the earliest is the tomb of Pir Hamza Sabzpush (12th century); the finest was that of Hasan ibn Kay Khusraw (...
