Erbil Citadel

The Erbil Citadel, locally known as Qellat, stands as a prominent tell or occupied mound in the heart of Erbil within the Kurdistan Region of Iraq. Rising between 25 and 32 meters above the surrounding plain, this oval-shaped archaeological settlement covers approximately 102,000 square meters. Recognized as a UNESCO World Heritage Site since 2014, it is frequently cited as the oldest continuously inhabited town in the world. Evidence of occupation on the site dates back to the fifth millennium BC, with clear artifacts from the Chalcolithic period and mentions in ancient Ebla tablets from around 2000 BC confirming its immense antiquity.

Throughout history, the citadel served as a vital center during the Neo-Assyrian Empire and later became a significant hub for Christianity under the Sassanian and Abbasid regimes. Its strategic importance faced a turning point after the Mongol siege and capture in 1258, which led to a gradual decline in its regional prominence. The architectural landscape has evolved significantly over millennia, though much of the original urban structure was modified or destroyed during the 20th century. Today, the site is partially ruined, with the Mulla Afandi Mosque remaining as the sole surviving religious structure atop the mound.

Despite periods of decay and modern urban pressures, the Erbil Citadel remains open to the public and stands as a testament to millennia of human civilization. It represents a unique layering of cultural history, from prehistoric pottery fragments found on its slopes to its role in various imperial eras. Currently controlled by the Kurdistan Region, the citadel continues to be an active archaeological site and a symbol of historical continuity, preserving the legacy of one of humanity's earliest urban centers amidst the modern sprawl of Erbil.
