The Hindu caves were constructed between the middle of sixth century to the end of the eighth century. The early caves (caves 17–29) were constructed during the Kalachuri period. The work first commenced in Caves 28, 27 and 19. These were followed by two most impressive caves constructed in the early phase – Caves 29 and 21. Along with these two, work was underway at Caves 20 and 26, and slightly later at Caves 17, 19 and 28. The caves 14, 15 and 16 were constructed during the Rashtrakuta period. The work began in Caves 14 and 15 and culminated in Cave 16. All these structures represent a different style of creative vision and execution skills. Some were of such complexity that they required several generations of planning and co-ordination to complete.
