Roça Sundy

Roça Sundy is a historic plantation estate on the island of Príncipe, once one of the largest cocoa producers in the archipelago during the colonial era. Its grand manor house, workers' quarters and processing buildings survive as a monument to the labour-intensive plantation economy that shaped the islands. The estate gained renown in 1919 when astronomers used a solar eclipse observed nearby to help confirm Einstein's theory of general relativity. Restored in part, it combines colonial architecture with a remarkable footnote in physics.
