Sankagiri Fort is a historical fort maintained by the Archaeological Survey of India. It is located 22 km from the city of Erode and 38 km from Salem. Fort was built in the 15th Century by the Vijayanagar Empire. It has 12 fort walls built on and built by the British. The fort served as a British tax storage facility for Kongu Nadu. It was an important military base for Tippu Sultan and later for the British army. This is because only one side of the hill is climbable, as all the others are too steep to climb. This has a death well, granary, two masjiths, 2 Varadhraja Perumal temples, former British Army administrative buildings, and cemeteries formerly used by armies that were stationed at the fort. Dheeran Chinnamalai was hanged by British in this fort.
