Question

Art of making bronze images was developed under the patronage of Kings

Answer 1

The ruins of several Mahayana Buddhist and Hindu shrines are located at Nagarjunakonda.[2] It is one of India's richest Buddhist sites, and now lies almost entirely under the Nagarjunasagar Dam. It is named after Nagarjuna, a southern Indian master of Mahayana Buddhism who lived in the 2nd century, who is believed to have been responsible for the Buddhist activity in the area. The site was once the location of many Buddhist universities and monasteries, attracting students from as far as China, Gandhara, Bengal and Sri Lanka.

Because of the construction of the Nagarjuna Sagar Dam, the archaeological relics at Nagarjunakonda were submerged, and had to be excavated and transferred to higher land on the hill, which has become an island.
