1. Nagarjuna Sagar Dam- Andhra Pradesh It is not just India's but world's largest masonry dam! Built over Krishna River, it is 1.6 kms long and 124 metres high, thus being symbolic of India's architectural and technological triumph over nature.
Amongst many other great dams and reservoirs built on the ferocious waters of Indian rivers stands one another great embankment on the Krishna river and its tributaries- the Nagarjuna Sagar Dam. While it’s a piece of wondrous creation of man and cement, what followed this exploration was even better as I got to the lakes of reservoir water and then the Nagarjunakonda Island. Earlier known to have been a Buddhist site, this island floats near Nagarjuna Sagar, near the dam, in the Guntur-Nalgonda district of Andhra Pradesh. The interesting ASI (Archaeological Survey of India) sites dug out in the past decade or so makes this an amazing stopover on my trip.
