Hoysala architecture is the building style developed under the rule of the Hoysala Empire between the 11th and 14th centuries, in the region known today as Karnataka, a state of India. Hoysala influence was at its peak in the 13th century, when it dominated the Southern Deccan Plateau region. Large and small temples built during this era remain as examples of the Hoysala architectural style, including the Chennakesava Temple at Belur, the Hoysaleswara Temple at Halebidu, and the Kesava Temple at Somanathapura. Other examples of Hoysala craftsmanship are the temples at Belavadi, Amruthapura, Hosaholalu, Mosale, Arasikere, Basaralu, Kikkeri and Nuggehalli. Study of the Hoysala architectural style has revealed a negligible Indo-Aryan influence while the impact of Southern Indian style is more distinct.
Temples built prior to Hoysala independence in the mid-12th century reflect significant Western Chalukya influences, while later temples retain some features salient to Chalukyan art 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.
