Lanka, Sri Lanka, and Possible Locations
The Lanka referred to in the still-extant Hindu Texts and the Ramayana (referred to as Ravana's Lanka), is considered to be a large island-country, situated in the Indian Ocean. The Ramayana, as also several other surviving Hindu texts, clearly state that Ravana's Lanka was situated 100 Yojanas (800 miles or around 1288 kilometres) away from mainland India. Some scholars have interpreted the content of these texts to determine that Lanka was located at the point where the Prime-Meridian of India passes the Equator. This island would therefore lie more than a hundred miles South-west of present-day country of Sri Lanka.
There has been a lot of speculation by several scholars, that Ravana's Lanka might have been in the Indian Ocean around where the Maldives once stood as a high mountain, before getting submerged in the Indian Ocean.
