The Berlengas Archipelago is located approximately 10 kilometers off the coast of Peniche in the Atlantic Ocean and has been a UNESCO Biosphere Reserve since 2011. The archipelago consists of the main island, Berlenga Grande, and smaller islet groups known as the Estelas and Farilhões. Its unique ecological status is derived from its role as a sanctuary for seabirds, including the common guillemot, which serves as the emblem of the reserve, and several endemic plant species adapted to the harsh maritime environment. Historically, the island is famed for the Fort of São João Baptista, a striking 17th-century fortification built to defend the coast and connected to the main island by a narrow stone bridge. The Duke of Bragança Lighthouse, built in 1841, stands at the island's highest point, providing vital navigation for vessels. The surrounding turquoise waters are exceptionally clear and rich in marine life, making it a premier destination for diving and snorkeling. Tourist access is strictly regulated to preserve the delicate balance of the natural environment and protect the nesting wildlife.
