Hoysala architecture is the building style in Hindu temple architecture 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.[1][2] These three temples were accorded UNESCO world heritage site status in 2023.[3] Other examples of Hoysala craftsmanship are the temples at Belavadi, Amruthapura, Hosaholalu, Mosale, Arasikere, Basaralu, Kikkeri and Nuggehalli.[4][5] Study of the Hoysala architectural style has revealed a negligible Indo-Aryan influence while the impact of Southern Indian style is more distinct.[6]
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.[7]
Hoysala architecture is classified by the influential scholar Adam Hardy as part of the Karnata Dravida tradition, a trend within Dravidian architecture in the Deccan that is distinct from the Tamil style of further south. Other terms for the tradition are Vesara, and Chalukya architecture, divided into early Badami Chalukya architecture and the Western Chalukya architecture which immediately preceded the Hoysalas. The whole tradition covers a period of about seven centuries began in the 7th century under the patronage of the Chalukya dynasty of Badami, developed further under the Rashtrakutas of Manyakheta during the 9th and 10th centuries and the Western Chalukyas (or Later Chalukyas) of Basavakalyan in the 11th and 12th centuries. Its final development stage and transformation into an independent style was during the rule of the Hoysalas in the 12th and 13th centuries.[8] Medieval inscriptions displayed prominently at temple locations give information about donations made toward the maintenance of the temple, details of consecration and on occasion, even architectural details.[9]
