The UNESCO World Heritage Committee began its 47th session this week in Paris, which will run until July 16. Among dozens of nominations, four stand out from the CPLP: Brazil, Guinea-Bissau, Mozambique, and Portugal.

The proposals range from natural landscapes to modern architecture and cross-border ecosystems. The session could redefine the map of the CPLP's cultural heritage, with the spotlight on four entries that reflect the diversity and potential of the Portuguese-speaking world.

While Portugal focuses on signature architecture, Brazil, Mozambique, and Guinea-Bissau boast natural landscapes of indisputable ecological value. Each nomination serves as a declaration of intent: to value, protect, and promote the memories and territories that make up the Community's identity.

UNESCO's selection could strengthen not only tourism and international prestige, but also cultural ties between Portuguese-speaking countries. More than just an award, World Heritage status is a collective obligation to care for and pass on to future generations.

By bringing together proposals from three continents, Lusophony reveals its geographic scope and pluralistic vocation. Natural heritage, contemporary architecture, and species migration ecosystems come together in an identity constellation of universal value.

Using heritage as a diplomatic tool strengthens the international standing of Portuguese-speaking countries. The CPLP's active participation in UNESCO represents an affirmation of cultural sovereignty.

By inscribing their territories and cultural assets on the World Heritage List, Member States strengthen their image and attract international solidarity. Heritage diplomacy strengthens bridges between nations with colonial pasts and shared futures.

The diversity of the nominations reflects each country's political and environmental priorities. Combining modern architecture, ecosystems, and indigenous culture, the CPLP projects a mosaic of complementary heritages. These proposals are not just acts of prestige, but commitments to preservation and appreciation.

Culture as a pillar of development is the foundation of modern diplomacy in the CPLP. Sharing best practices and creating cooperation networks among member states are essential. UNESCO serves as a platform and arbiter for this global cultural dialogue.

The simultaneous presence of four Portuguese-speaking states in this session demonstrates the vitality of South-South cooperation. Lusophony asserts itself not only as a legacy, but also as a project for the future. With these applications, the CPLP reinforces its international relevance and embraces heritage as a strategic asset for sustainable development.

The works of architect Álvaro Siza Vieira are the face of Portugal's World Heritage candidacy. The selection includes seven buildings spread across Porto, Lisbon, Matosinhos, and Caminha.

Among them are the Portuguese Pavilion, the Faculty of Architecture of the University of Porto, and the Boa Nova Tea House. The proposal reflects Portuguese modernism and architectural integration into the urban landscape.

Portugal intends to assert its contemporary architectural identity as a cultural asset of universal value. The UNESCO Committee, however, recommended that a technical review be carried out, but without ruling out future approval.

The application is supported by academia and cultural institutions that consider Siza Vieira's work a World Heritage Site. His spatial sensitivity and dialogue with the surrounding environment are considered examples of environmentally and socially conscious architecture.

The Bouça neighborhood and the Serralves Museum, also included, bear witness to the evolution of social housing and modern culture in the Portuguese-speaking world. The inclusion of these spaces in dense urban areas underscores the city's appreciation as a living organism.

If accepted, Portugal will strengthen the presence of modern architecture within UNESCO, which until now has been dominated by ancient or natural monuments. This nomination recognizes the Portuguese-speaking world's contribution to the development of a modern architectural language with local roots and global ambitions.

The Bijagós Archipelago, proposed by Guinea-Bissau, represents one of the largest ecological reserves in the African Atlantic. Comprising more than eighty islands, the territory boasts unique biodiversity and a high density of sea turtle nests.

Recognized as a sanctuary for migratory birds, the Bijagós ecosystem lies at the center of the East Atlantic flyways. The project presents a landscape of coexistence between humans and nature, preserved by traditional sustainable practices.

Since 2013, the country has been fighting for this recognition, strengthening environmental legislation and community management mechanisms. Legal protection has been expanded to guarantee the integrity of habitats and local culture. According to the report, IUCN, the archipelago is:

“Probably the most important site in Africa and one of the most important in the world for sea turtle nesting and the second most important food gathering site in Africa for the East Atlantic migration route, which is of global importance for migratory birds.”.

The UNESCO Committee welcomes the nomination's progress, highlighting the ecological and cultural importance of the territory. The participatory management model is seen as an example for other regions with sensitive heritage sites. The involvement of local communities is crucial to ensuring the sustainability and balance of ecosystems.

At the same time, Brazil presents the Peruaçu Caves National Park, in Minas Gerais, with cave paintings and geological formations of great value.

The Peruaçu River, one of the tributaries of the São Francisco River, had its natural course blocked by a large limestone massif. Over time, the erosive action of the waters carved the limestone as it tried to find a way out. The effects of time have resulted in a series of caves, many still virgin, that have attracted speleologists in search of as-yet uncatalogued grottoes.

Brazil's candidacy is subject to approval by the Xakriabá indigenous people who inhabit the region. UNESCO demands guarantees that the rights of indigenous peoples are respected.

Mozambique proposes the registration of Maputo National Park as a World Heritage Site. The territory includes forests, wetlands, and pristine coastlines. This park is connected to the iSimangaliso Wetlands Park in South Africa, which already has UNESCO status. If approved, a transboundary committee will be created for joint management.

The goal is to ensure species mobility and the comprehensive protection of shared ecosystems. Mozambican authorities have strengthened surveillance and cooperation with regional institutions, as the park boasts a high density of protected species and represents a vital ecological corridor in southern Africa.

The UNESCO Committee praises the proposal for promoting environmental cooperation between neighboring states. International recognition could attract sustainable investments and eco-tourism projects.

The nomination stands as a symbol of the CPLP's environmental commitment and regional integration. The park's biological diversity and educational potential justify its inclusion as a World Heritage Site.

Protecting this natural space will also be an opportunity to consolidate inclusive and sustainable management practices.

The CPLP's heritage gains prominence on the international agenda through UNESCO. The nominations under review reflect a symbolic capital that transcends borders. Natural landscapes, avant-garde architecture, and cross-border ecosystems affirm Lusophony as a common heritage of humanity.

The Committee's 47th session may enshrine the CPLP's diversity as a universal value. Culture, environment, and cooperation are pillars that strengthen Portuguese-language diplomacy in the XNUMXst century.
