One has to take the Gudlur route from Aihole, which is approx 30 kms and further onwards it is 22 kms one comes into Gajendragarh one of the massive forts. There two more fortifications enroute to this fort along with a Kalkakaleswar temple.
The area turned out have six more fortifications. Looking at the size and shape of the fortifications, I am inclined towards these being sarais or caravan stations than forts.

The northernmost fortification overlooks Aihole. The remaining five are concentrated around Gudur.
