The plantations emerged from the archipelago's second plantation economy. After sugar, which had made São Tomé one of the first centers of Atlantic slavery, coffee and cocoa repositioned the islands on the trade routes of the 19th century. From the 1850s onwards, the large estates brought together land, machinery, warehouses, roads, housing, and authority in a single system.

The layout of the buildings revealed who was in charge and who obeyed. The administrator's house occupied the dominant point, the courtyards organized production, and the slave quarters crammed working families into minimal spaces. Hospitals, schools, and chapels emerged later, often under external pressure, but they also served to keep the workforce alive and disciplined.

Slavery was abolished in 1875, but legal freedom did not end the economic system. Contracts, debts, surveillance, and obstacles to return bound thousands of workers to the estates. Contingents arrived from Angola, Mozambique, and Cape Verde, bringing with them the languages, beliefs, and memories that helped shape modern São Toméan society.

At the beginning of the 20th century, the archipelago occupied a central position in world cocoa production. The wealth flowed to Portugal and European markets, while the human cost remained on the plantations. The chocolate consumed far from the islands depended on people subjected to long journeys, unsanitary housing, punishments, diseases, and prolonged separations from their African homelands.

UNESCO recognition should preserve the walls, roofs, and machinery without hiding the system that gave rise to them. When a visit begins on the manor house's veranda and ends at the cocoa dryer without passing through the slave quarters, the route repeats the colonial hierarchy instead of explaining how the wealth was produced and who paid its human cost.

In UNESCO's decision, the expression "forced migration" occupies a central place because it draws attention to the people brought to the archipelago. Many workers did not freely choose their destination, contract, or place of residence, and encountered obstacles that prevented them from returning to their homelands after years of work on the properties.

The history of the plantations belongs to those who planted, harvested, transported, and processed the cocoa, and to the children who inherited the territories marked by inequality. This memory rarely appears in its entirety in administrative archives because colonial documents prioritized production, discipline, expenses, and the accounts of the landowners.

The workers appeared in the records as numbers, origins, available labor, or health problems. Recovering their names requires cross-referencing documents, oral testimonies, cemeteries, photographs, letters, and household objects. This work must restore people's identities without turning their lives into decorations for exhibitions or tourist visits.

The buildings help to understand the order imposed on the plantations. The towers, the bells, the lookout points, and the layout of the courtyards allowed for monitoring the movements and rhythms of work. The distance between the houses of the chiefs and the workers' barracks reflected a social boundary that must be shown to visitors with clarity and precision.

The protection of the plantations must also acknowledge the cultures born from displacement. The languages, religious practices, cooking methods, music, and nets brought from other countries helped shape the communities of São Tomé. Without recovering these memories, UNESCO risks giving visibility to an incomplete version of history.

International recognition can attract visitors, funding, and investment, and increase the value of nearby properties and land. The attention given by UNESCO can also favor commercial activities linked to cocoa and coffee. This increased value raises an uncomfortable question about who will reap the greatest benefits from the new status.

Without clear rules, the income may initially end up in the hands of concessionaires, tour operators, and landowners. The plantations belong to the State, but several are managed under concessions. The approved registration conditions stipulate that private interests should not prevail over conservation or the living conditions of the communities.

The works cost money, but whoever finances the restoration of a building can influence access, employment, and how the story is told. In Príncipe, the transformation of Sundy and Belo Monte into tourist accommodations allowed for the preservation of some of the buildings, but also interrupted the continuity of community life in those places.

This precedent should serve as a warning to prevent other plantations from being emptied and converted into tourist areas while the residents are displaced. It was these communities that remained on the properties during the years of abandonment and preserved a human presence in places that the State, the former owners, and investors had allowed to deteriorate.

Participation cannot be limited to consultations held once contracts are already prepared. Residents must be integrated into management committees, understand the terms of the concessions, and have control over the buildings, visitor routes, and income distribution. UNESCO-recognized protection will only be legitimate when it concretely improves the lives of communities.

Tourism can help preserve buildings that the state is unable to restore. The international attention generated by UNESCO can also create jobs, stimulate handicrafts, promote coffee and cocoa, and extend the stay of visitors. These benefits, however, depend on truth, respect for communities, and the way history is told.

A hotel located on a plantation should not only value the landscape, the forest, and the architecture while erasing the colonial system that sustained the comfort offered to visitors today. Each visit should explain the production cycle, from the arrival of the workers and their distribution to the accommodations, to the surveillance, harvesting, drying, transport, and export.

The manor houses should be presented alongside the slave quarters. The hospitals need to be explained as responses to complaints about working conditions and as instruments used to keep the workforce functional. The routes should reveal the complete functioning of the properties without focusing attention only on the most imposing buildings.

To tell this story, museums are needed on the plantations themselves, accessible archives, signage, trained guides, and content produced by São Toméan institutions. There should also be spaces for testimonies from descendants and exhibitions about Angola, Mozambique, and Cape Verde, countries linked to the forced migration that sustained the plantation economy.

Barracks, cemeteries, places of punishment, and objects cannot be transformed into backdrops for photographs or private parties. The dignity of the dead and the survivors demands limits. When the past is hidden to protect the tourist image of a destination, inscription on the UNESCO list ceases to serve education and begins to serve only the market.

With its inscription on the UNESCO World Heritage list, São Tomé and Príncipe gained greater visibility, but it also imposed obligations on the São Toméan state. The decision requires adequate protection zones, a national management committee, works to stabilize structures at risk, a plan for organizing archives, and evaluations of new projects planned for the protected areas.

The planned monitoring prevents the celebration from ending with the inscription ceremony. Dilapidated structures need repairs, maps must be accurate, and private projects require oversight. Protection will be fragile if the Directorate of Culture lacks the necessary technicians, budget, and authority to enforce the rules on public and private entities.

The sovereignty of memory depends on the capacity to investigate and teach. São Tomé and Príncipe needs to train conservators, archaeologists, historians, archivists, architects, and managers. Foreign partnerships can contribute, but they should not retain the exclusive power to decide how the plantations will be studied, presented, and explained.

The potential future inclusion of Roça Agostinho Neto shows that protection cannot be limited to the six inscribed sites. Many properties remain outside the recognized area, even though they contain buildings, communities, and histories. National policy should avoid a division between six protected sites and dozens of abandoned ruins throughout the archipelago.

During colonialism, cocoa and coffee left the islands while wealth and authority remained abroad. Now, resources, knowledge, and decision-making power must remain in the country. UNESCO-supported preservation will be an act of sovereignty when São Tomé and Príncipe leads the narrative and shares the benefits generated locally.

UNESCO has recognized the plantations as representing a colonial system of production, forced migration, and coercive labor. The decision offers São Tomé and Príncipe an opportunity to preserve the architecture and demand that the chocolate and coffee sectors acknowledge the African labor that sustained their wealth.

Inclusion on the heritage list will only be effective if communities participate in its management and receive the resulting benefits. Doing justice requires investment in archives, schools, research, and conservation, as well as public contracts and limits on tourism.

It also demands a transparent distribution of income and the courage to show the slave quarters in contrast to the manor houses, the cemeteries in contrast to the hotels, and the names of the workers in contrast to the wealth they helped to create.
