Narkandam, Andaman Islands, India (Google Maps ⧉, OpenStreetMap ⧉)

"a strange weird‐looking island, a steep and regular volcanic cone, which rises covered with forest to a height of 2150 feet ... bears the name Narkandam, in which one cannot but recognise नरक, Narak, “Hell”; perhaps Naraka-kuṇḍam, “a pit of hell.”"
