Khanzad Castle is situated 22 km from Erbil, on the road between Erbil and Shaqlawa. Constructed during the Soran Emirate in the 16th century under the rule of Princess Khanzad and her brother Prince Suleiman Beg, the citadel is about 40m tall and sits on top of a small hill. The castle has kept much of its original shape and has four round towers at each of its four corners; made of stones and gypsum, it is a stunning archaeological site.
