Located on Príncipe island, Roça Sundy is famous both for its cocoa production and the historical site where Arthur Eddington conducted observations proving Einstein's theory of general relativity. It is one of six roças recognized as UNESCO World Heritage sites. The Roças are historic agricultural plantations in São Tomé and Príncipe that were established by the Portuguese in the 19th and 20th centuries for coffee and cocoa production.
