The Empires and Kingdoms that came to rule from Karnataka were prolific builders. The Badami Chalukyas spawned the "Vesara" style of architecture and experimented with several myriad styles with frequent intermixing of "Nagara" and Dravida concepts. This period is the beginning of Hindu rock cut architecture, both in stand alone and cave temple idioms, numerous examples of which exist in Pattadakal, Aihole and Badami - (Badami Cave Temples). Their successors, the Rashtrakuta created master piece temples further favoring Dravidian concepts. Most of their temples in Karnataka are scattered over northern Karnataka districts.
