The Kirkuk Citadel (Arabic: قلعة كركوك; Kurdish: قەڵای کەرکووک; Turkish: Kerkük Kalesi) is a citadel and associated structures located in the center of Kirkuk, Iraq, and is considered to be the oldest part of the city. The citadel stands on a 40-metre-high (130 ft) tell, located on a plateau across the Khasa River. Although most of the citadel was demolished, parts of it, including mosques, tombs, and houses, still remain intact. Historically a majority Turcoman but also a multicultural city religiously, economically, and ethnically, the citadel contained many markets, mosques, some dating back as far as the Golden Age of Islam, bearing the name of many distinguished locals, and many Sufi monasteries (Known in Iraq generally as takiyya) or Sufi establishment due to the growth of the Qadiriyya Order in the area. There are also many sites dedicated to Christian and Jewish worship.
