Siirt is a province in Southeastern Anatolia, situated about 224 kilometers (140 miles) northwest of Mardin and separated by the Tigris River. This region that was once under Persian, Roman, Byzantines and Abbasid influence also served as an economic center during this time.
The settlement of many civilizations in the Botan stream valley is noted as early as around 3000 BC. The Hurri and Subarru, two native groups that were settled there at that time, witnessed Assyrian and Med domination during the 7th century BC, Persian Empire dominance in the 6th century BC, Roman and Byzantine Empires ruling from 395 to 554 AD respectively. Later it was ruled by Mongolians who occupied it for a few years before being taken over by Ottomans with them until 1514 when they finally conquered this region and took control of it.
The name Siirt is thought to derive from "Keert" which means “city” in the Keldani language. The tombs of Veysel Karani and Ismail Hakki connect the past with our time, as pieces of Islamic civilization.
The Grand Mosque was built by Mahmut, the Seljuk ruler in 1219. In 1260, Mucahit Ishak Lindar added annexes to the original structure and made some improvements on it. The foundation reconfigured and restored the mosque's pulpit, which is now exhibited at the Ethnologic Museum in Ankara. The shrine has a single balcony minaret embellished with turquoise china work. However, these decorations can't avoid climatic conditions from eroding them over time; this is true for all structures in Turkey that were created before climate change became so prevalent. The building's magnificent dome sits at its center with smaller domes circling around it on all four sides.
