Ganja is one of the oldest cities in the Caucasus, and has long been one of the most important in Azerbaijan.The name Ganja means wide derived from a word "gan" (wide). Ganja is an ancient city of Azerbaijan which is settled in the fifth century . The reference to Ganja could be found in the book "Kitabi Dada Korkut" ( the historical literature work of Oghuzs, the ancestors of Azerbaijani turks.) Having been subjected to a seemingly endless stream of invading armies, its name has changed repeatedly over the years. The historical name, Ganja, was restored once again upon Azerbaijan's independence in 1991. With a population of over 500,000 it's currently the country's second-largest city. Ganja was the birthplace of the famous Central-Asian poet Nizami, and his tomb is a popular site for visitors.
