Erbil, also spelled Arbil, locally called Hewlêr by the Kurds, is the capital city of Iraqi Kurdistan and the most populated city in the Kurdish inhabited areas of Iraq. It is located approximately in the center of the Iraqi Kurdistan region and north of Iraq.
The Erbil Citadel, also known as Hawler Castle, is an artificial mound and the historical city center of Erbil, located in what’s now the Kurdistan region of Iraq. The mound was slowly formed as a result of human occupation starting about 6,000 years ago, eventually rising 100 feet (30 meters) tall as mud-brick structures and other debris crumbled and compacted into the ground below. It’s now enshrined as a UNESCO World Heritage site, surrounded by a city of more than 850,000 people.
