Roça Sundy: Príncipe's Historic Plantation Hotel
Where Einstein’s theory of relativity was confirmed in 1919. A restored 19th-century cocoa plantation now operating as one of Africa’s most distinctive heritage hotels.
ABOUT THE HOTEL
Roça Sundy: Where Einstein Confirmed Relativity
Roça Sundy is one of the most historically significant hotels in Africa. The property is a fully restored 19th-century roça (Portuguese colonial plantation house) at the heart of the Sundy cocoa estate on Príncipe Island, and the site where Sir Arthur Eddington’s 1919 solar eclipse expedition took the photographs that confirmed Einstein’s general theory of relativity, making Einstein a global household name overnight.
Today the main casa grande and surrounding outbuildings have been restored as a heritage hotel by the HBD Príncipe Collection. Guests stay in 15 individually styled rooms spread across the colonial buildings, dine in the historic main house, swim in a tropical pool, tour the working cocoa plantation, and visit the small on-site museum dedicated to the Eddington expedition. The whole estate sits inland in Príncipe’s rainforest, a counterpoint to the beach properties at Sundy Praia and Bom Bom.
The smartest Príncipe itinerary pairs Roça Sundy with one of the beach properties (Sundy Praia or Bom Bom). 2 nights at the plantation gives you history, cocoa culture, and the inland forest. Then 3-4 nights on the beach. Sundy Praia is closest geographically.

Roça Sundy: Frequently Asked Questions
What is the Einstein connection at Roça Sundy?
On May 29, 1919, British astronomer Sir Arthur Eddington led a solar eclipse expedition to Príncipe Island and set up his observation equipment at Roça Sundy. The photographs his team captured of stars near the eclipsed sun showed light bending exactly as Einstein had predicted in his general theory of relativity, providing the first observational confirmation of Einstein’s theory and making him a global celebrity overnight. The estate today houses a small museum dedicated to the Eddington expedition.
How do I get to Roça Sundy from São Tomé?
Roça Sundy is on Príncipe Island, reached by a 40-minute scheduled flight from São Tomé International Airport (TMS) to Príncipe Airport (PCP). The hotel includes airport transfers from PCP. Staff meet you and drive ~25 minutes inland to the plantation. Total door-to-door from São Tomé city: about 1.5 hours.
Is Roça Sundy beachfront?
No. Roça Sundy is an inland plantation hotel, sitting about 1.5 km from Sundy Praia beach in the rainforest. This is intentional and part of the property’s appeal: it offers a heritage and forest experience rather than a beach stay. Guests who want beach access typically combine Roça Sundy with Sundy Praia or Bom Bom Island Resort for variety.
Can I visit Roça Sundy as a day trip from Sundy Praia or Bom Bom?
Yes. If you’re staying at Sundy Praia (just down the road) or Bom Bom Island Resort, Príncipe Collection arranges cocoa plantation tours and lunch visits to Roça Sundy as a half-day excursion. Many guests do this without staying overnight. However, the property is special enough that 1-2 nights here is recommended if your trip allows.
How do I book Roça Sundy?
Message São Tomé Life and we’ll help you sort it. We can help with availability, rates, the heritage rooms, and the inter-island flights from São Tomé. It’s small (15 rooms) and often paired with the beach properties, so ask 2 to 3 months ahead.
