India: Adam's Bridge

Rama Setu, also known as Adam's Bridge, is a chain of limestone shoals, between Rameswaram Island, off the southeastern coast of Tamil Nadu, India, and Mannar Island, off the  northwestern coast of Sri Lanka. Geological evidence suggests that this bridge is a former land connection between India and Sri Lanka.
