Western Chalukya architecture is the distinctive style of ornamented architecture that evolved during the rule of the Western Chalukya Empire in the Tungabhadra region of central Karnataka, India, during the 11th and 12th centuries. Western Chalukyan political influence was at its peak in the Deccan Plateau during this period. The centre of cultural and temple-building activity lay in the Tungabhadra region, where large medieval workshops built numerous monuments. These monuments, regional variants of pre-existing dravida (South Indian) temples, defined the Karnata dravida tradition. Temples of all sizes built by the Chalukyan architects during this era remain today as examples of the architectural style.Most notable of the many buildings dating from this period are the Mahadeva Temple at Itagi in the Koppal district, the Kasivisvesvara Temple at Lakkundi in the Gadag district, and the Mallikarjuna Temple at Kuruvatti and the Kallesvara Temple at Bagali, both in the Davangere district.Other monuments notable for their craftsmanship include the Siddhesvara Temple at Haveri in the Haveri district, the Amrtesvara Temple at Annigeri in the Dharwad district, the Sarasvati Temple in Gadag, and the Dodda Basappa Temple at Dambal, both in the Gadag district.The surviving Western Chalukya monuments are temples built in the Shaiva, Vaishnava, and Jain religious traditions. None of the military, civil, or courtly architecture has survived; being built of mud, brick and wood, such structures may not have withstood repeated invasions.
