Sao Tome’s UNESCO Roças Face the Hard Test of Preserving Memory Without Erasing Communities

Sao Tome and Principe’s newly listed UNESCO roças are now facing the harder part of World Heritage status: turning recognition into preservation without turning living communities into decoration. Africanews reported on August 30 that the former plantation estates, known locally as roças, are drawing fresh interest from preservation advocates and private investors after six of them were added to the UNESCO World Heritage List last month. The opportunity is real, but so is the risk. These sites are not empty monuments. They are places of memory, labour, forced migration, community life and unresolved economic history.

The UNESCO inscription covers six estates across the islands of Sao Tome and Principe: Monte Cafe, Agua Ize, Diogo Vaz, Sao Joao, Sundy and Belo Monte. UNESCO describes the serial property as a colonial agricultural system built around coffee and cocoa production, combining agricultural land, industrial facilities, worker housing and social infrastructure. The agency emphasizes that the system was based on forced migration and labour from the late 19th century through the mid-20th century.

That framing matters. World Heritage status can bring attention, tourists, funding and restoration. But if the story is reduced to picturesque ruins and boutique hotels, the inscription will fail its most important purpose. The roças matter because they reveal how global commodity wealth was organized through coercion, race, migration and control. Their value is not only architectural. It is historical and moral.

A first World Heritage listing

The July 2026 inscription was a milestone for the island nation. UNESCO said Sao Tome and Principe was among new countries joining the World Heritage List this year, giving the archipelago its first such recognition. For a small African island state in the Gulf of Guinea, that visibility can change how cultural policy, tourism planning and development finance interact.

Small island economies often struggle to diversify. Sao Tome and Principe has long relied on agriculture, aid, public administration, remittances and a limited tourism sector. Its cocoa heritage is internationally recognized, but heritage tourism requires more than branding. It needs access roads, interpretation, conservation skills, trained guides, local businesses, fair land arrangements and careful management of visitor flows.

The roças offer a distinctive tourism asset because they link landscape, architecture, agriculture and social history. They include processing buildings, avenues of worker housing, chapels, hospitals, stables, managers’ houses and agricultural land. Some estates remain partly inhabited by descendants of former workers. Others are abandoned or deteriorating. That variety makes preservation complex. A site can be a ruin, a home, a hotel, a farm, a museum and a trauma landscape at the same time.

The Sundy example

Africanews focused partly on Sundy plantation on Principe island, where Conceicao Moreno, a National Assembly member and descendant of Cape Verdean contracted workers, described a strong personal connection to the site. His family history reflects a wider pattern. After Portugal abolished slavery, plantation labour did not become free in any simple sense. Workers were brought, often under coercive conditions, from Angola, Mozambique, Cape Verde, Gabon and Congo, among other places.

That history is why preservation cannot be only about walls. The roças carry family memory. They also carry evidence of a system that replaced formal slavery with contracts and control that kept workers tied to plantations in harsh conditions. Any restoration plan that treats that past as background detail will miss the central story.

Sundy also shows the investment question. Africanews reported that HBD, an investment fund founded by South African entrepreneur Mark Shuttleworth, owns two former roças on Principe and has converted or is restoring parts of the estate for hotel use. The old plantation owner’s mansion has already become a five-star hotel, while workers’ houses are expected to become extra rooms once renovation is complete.

Private investment can preserve buildings that the state alone may not have the resources to restore. It can create jobs, train artisans, support maintenance and bring global visitors. But the terms matter. Who benefits from the new value? Are former worker communities included in planning? Are residents protected from displacement? Is the forced-labour story told clearly to visitors? Are local guides, farmers, artists and small businesses part of the economic chain? These are not secondary questions. They determine whether heritage development is fair.

A 10-year restoration challenge

Sao Tome and Principe has launched a 10-year plan to restore the roças and find new uses for them, according to Africanews. Culture chief Emir Boa Morte said UNESCO recognition is already helping mobilise the population and that more roças could eventually join the list. He also insisted that investment should not erase history.

That commitment should now be translated into enforceable policy. Restoration standards should protect original materials and spatial layouts where possible. Interpretation should explain both agricultural innovation and labour exploitation. Community consultation should be documented. Any commercial concession should include obligations for conservation, local hiring, training, public access and historical education.

The scale of the task is large. Boa Morte said there are still around a hundred roças, although many have disappeared, merged or deteriorated. Africanews described most as run-down, overgrown or unsanitary, even while some remain inhabited. This means preservation cannot be limited to the six UNESCO-listed sites. A national strategy needs to decide which estates become museums, which remain residential, which can support tourism, which require emergency stabilization and which need basic services for existing residents.

Climate risk is part of heritage risk

The preservation challenge is also environmental. UNESCO’s work on Sao Tome and Principe has warned that climate-related hazards such as floods, coastal erosion, landslides and storms threaten cultural and natural heritage, including roças, archives and museums. For an island state, climate resilience is not a separate file from heritage conservation. It is part of whether buildings survive.

That matters for investment planning. Restoring a roof without managing drainage may not protect a site through heavier rains. Opening a hotel without protecting surrounding landscapes may weaken the heritage value that attracts visitors. Maintaining worker housing as heritage without improving sanitation for residents would be ethically weak. The strongest strategy is integrated: conservation, climate adaptation, housing dignity, tourism and agriculture should reinforce each other.

Sao Tome’s biosphere context also adds value. UNESCO notes that Sao Tome island contains rich biodiversity, endemic species, agro-forestry landscapes and traditional livelihoods tied to fishing, cocoa and coffee. If managed well, the roças can connect cultural tourism to sustainable agriculture and conservation. Visitors should not only see buildings. They should understand how cocoa, coffee, forests, labour and island ecology shaped the country.

A wider African heritage lesson

The roças join a broader African debate about how to preserve places connected to exploitation without turning pain into spectacle. Across the continent, heritage sites tied to slavery, colonial extraction, mining, forced labour or conflict face the same tension. Recognition can bring money and pride, but it can also sanitize the past if tourism becomes the main lens.

The best heritage policy does not ask communities to choose between memory and development. It makes development accountable to memory. That means telling uncomfortable stories accurately, preserving material evidence, supporting descendants and local residents, and ensuring economic benefits do not flow only to outside investors or central institutions.

For Sao Tome and Principe, this is especially important because the roças are foundational to national history. They shaped settlement patterns, social structure, agricultural identity and the country’s place in global cocoa and coffee supply chains. Preserving them is not nostalgia. It is a way of documenting how the modern economy was built and who paid the price.

The bottom line

UNESCO recognition gives Sao Tome and Principe a rare chance to build a serious heritage economy around the roças. It can support restoration, tourism, local employment and international visibility. But the listing is only a beginning. The real test is whether preservation protects both architecture and truth.

The roças should not become polished stages emptied of the people and histories that give them meaning. They should become places where visitors, residents and policymakers confront the full story of forced migration, plantation labour, cocoa wealth, colonial control and post-independence decline. If Sao Tome and Principe can do that while creating jobs and restoring buildings, the UNESCO inscription will become more than a label. It will become a model for African heritage that refuses to separate memory from development.
