The industrial city of Unnao in the Indian state of Uttar Pradesh functions as the headquarter of the Unnao district. It has three industrial suburbs around it. Unnao is a part of Central Ganges Plain and the region falls under the Kanpur-Lucknow Counter Magnet Area. A new satellite town of Unnao by the name of Trans Ganga City is being built to develop Unnao as a major infrastructural and industrial and hub. Unnao was earlier known for its dense forest cover until the 12th century when Godo Singh of the Rajput clan cleared the forest and established a settlement in the area called Sawai Godo. This town went into the hands of the rulers of the Kannauj. A governor was appointed to look after the place, but he was killed by a Bisen Rajput called Unwant Rai Singh. Thus the area passed on to the usurper Unwant Rai Singh, who built a fort and renamed the place as Unnao after himself. Unnao is known for its leather, chemical industries and mosquito nets. Tanning is the biggest contributor to Unnaos economy, followed by the dye and printing of mosquito nets. The city has many historical buildings and structures apart from beautiful lakes and scenic landscapes.
