Temples built prior to Hoysala independence in the mid-12th century reflect significant Western Chalukya influences, while later temples retain some features salient to Western Chalukya architecture but have additional inventive decoration and ornamentation, features unique to Hoysala artisans. Some three hundred temples are known to survive in present-day Karnataka state and many more are mentioned in inscriptions, though only about seventy have been documented. The greatest concentration of these are in the Malnad (hill) districts, the native home of the Hoysala kings.
