The town of Zakho was known to the ancient Greeks. In 1844. the traveller William Francis Ainsworth commented: "The appearance of Zakho in the present day coincides in a remarkable manner with what it was described to be in the time of Xenophon."
One of Zakho's famous landmarks is the Delal Bridge. It is made with large stones which adds to the aesthetic value of the bridge and makes it a source of many theories as to how it was built. (The stones are very large, and there was no machinery available at that time.)
