Sri Lanka, formerly known as Ceylon, is a teardrop-shaped island nation in the Indian Ocean covering 65,610 square kilometers, separated from India by the narrow Palk Strait (just 35 km wide). The island has been a crossroads of maritime trade for millennia, known for spices, tea, gemstones, and its strategic position on Indian Ocean shipping lanes. Its diverse landscape includes tropical beaches, ancient ruins (such as the 5th-century rock fortress of Sigiriya), lush hill country, and one of Asia's highest biodiversity levels per unit area.
