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.
Sankagiri Fort is steeped in history. The boulder-strewn rocky hill and the ruins of the fort make for a charming locale and from the hill you can enjoy sweeping views of the surrounding landscape. You can ascend the fort from two flanks of the hill; one is relatively easy but the other is tough. There are two oil godowns at the fort and a Varadharaja temple. This apart there are two official buildings and a memorial park.
From Sankaragiri, you could visit the Mettur Dam. The charming hill resort, Yercaud is close by too.
