Hampi Boulders
This site is found in India, in the central/southern portion of the peninsula. The rocks are truly ancient; they are metamorphosed granites that are part of the Dharwar Craton. This craton is a stable piece of crust assembled about 2.7 billion years ago after a series of collisions and outbreaks of volcanism. Similar gneisses outcrop in a number of places in the central part of India.
This granitic outcrop has hosted a variety of cities during the past millennia; four dynasties ruled a kingdom called Vijayanagar, with its capitol city found here. After the fall of that kingdom, the area lay neglected, leaving a variety of structures and artifacts from hundreds of years ago still in tact in the area.
