During the growth of ancient civilization, ancient technology was the result of incredible development in ancient engineering and medicine in ancient times.
However many ancient inventions are forgotten, especially in India.
Indian architectures, especially the temples in India are the most wonderful buildings which are built in a perfect orientation in older days which even modern technology fails.
