>[!abstract] >Adam's Bridge, also known as Rama's Bridge or Rama Setu, is a chain of natural limestone shoals between Pamban Island, also known as Rameswaram Island, off the southeastern coast of Tamil Nadu, India, and Mannar Island, off the northwestern coast of Sri Lanka. Geological evidence suggests that the bridge was formerly a land connection between India and Sri Lanka. > >The feature is 48 km long and separates the Gulf of Mannar (southwest) from the Palk Strait (northeast). Some regions of the bridge are dry, and the sea in the area rarely exceeds 1 metre in depth, making it quite difficult for boats to pass over it. > >The name Adam's Bridge … appears to have been premised on the Islamic belief that Adam's Peak — where the biblical Adam fell to earth — is located in Sri Lanka, and that Adam crossed over to peninsular India via the bridge after his expulsion from the Garden of Eden. The ancient Sanskrit epic Ramayana (8th century BCE–3rd century CE) mentions a bridge constructed by the god Rama to reach the island Lanka and rescue his wife Sita from Ravana (Wikipedia, 2025). >[!related] >- **North** (upstream): — >- **West** (similar): — >- **East** (different): — >- **South** (downstream): —
