How many caves are there in Ajanta?

Ajanta dates from 100 B.C. while Ellora is younger by some 600 years. The village of Ajanta is in the Sahyadri hills, about 99 kms. From Aurangabad; a few miles away in a mammoth horseshoe-formed rock, are 30 caves overlooking a gorge, each forming a room in the hill and some with inner rooms.
