4. Ajanta and Ellora Caves

 Astonishingly carved into hillside rock in the middle of nowhere are

the Ajantaand Ellora caves. There are 34 caves at Ellora dating from

between the 6th and 11th centuries AD, and 29 caves at Ajanta dating

back to between the 2nd century BC and 6th century AD. While the Ajanta

caves are rich in paintings and sculpture, the Ellora caves are renowned for

their extraordinary architecture. The most incredible thing about these caves

is that they were crafted by hand, with only a hammer and chisel.
