Porto Santo Biosphere Reserve: island, sea and clay-roofed houses

Porto Santo Biosphere Reserve, designated by UNESCO in 2020, combines land and sea within the Madeira archipelago. The island, surrounding islets and marine area should be understood together. It is separate from Santana on Madeira island and belongs to the Man and the Biosphere programme, which connects conservation, research and sustainable development.

Beyond the beach

The sandy beach is a landmark, but it does not explain the whole territory. Pico Branco, volcanic landforms, cliffs and offshore islets add different environments. Plants characteristic of the island and seabirds reward careful observation, without making sightings a guaranteed part of a visit.

Porto Santo’s network of marine protected areas and Natura 2000 sites have their own protection instruments. UNESCO designation does not replace those regimes or mean every islet and habitat is open to visitors.

Architecture rooted in local materials

The casas de salão use local clay to cover their roofs. They express adaptation to available materials and climate, and differ from Santana’s thatched houses. The muros de croché, stone walls associated with vineyards, show another way of arranging farmland and working with stone.

Read houses and fields as evidence of everyday life, beyond the island’s beach image. Our Madeiran vernacular architecture guide provides context for comparing building solutions across the archipelago.

Planning your discovery

The official reserve information introduces natural and cultural heritage; the Casa de Salão visitor page offers a starting point for local architecture. Before walking, check route status and any booking requirements, fees and restrictions in the official hiking information. Check weather and transport too: the territorial reserve has no single opening time or ticket.
