Western Chalukya architecture, also known as Kalyani Chalukya or Later Chalukya architecture and broadly classified under the Vesara Style, is the distinctive style of ornamented architecture that evolved during the rule of the Western Chalukya Empire in the Tungabhadra region of modern 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 temples, form a climax to the wider regional temple architecture tradition called Vesara or Karnata dravida. Temples of all sizes built by the Chalukyan architects during this era remain today as examples of the architectural style.
