Green Shores: Exploring the Bay of Biscay and Iberian Coastline

Bordeaux stretches along the banks of the Garonne river, in South-West France. Its rich wine tradition makes it the world capital of wine. Let yourself be carried away by the history of the Port de la Lune, made a UNESCO World Heritage site for its prestigious classical architecture. On the famous Place de la Bourse, the past and the present unite: here you can observe the majestic old buildings reflected in the contemporary Miroir d’eau creation.

A renowned seaside resort in the South West of France, Saint-Jean-de-Luz is a picturesque and authentic town with a rich history. In particular, King Louis XIV married Maria Teresa in the famous Saint Jean the Baptist church in 1660. The seafront unveils stunning views, between the Basque architecture and the Cantabrian Sea. An unforgettable bay, which was frequented in the 17th century by privateers and wealthy ship-owners.

Facing the Bay of Biscay, its backdrop a natural setting that combines sea and mountain, Santander rolls out along a huge bay on the northern coast of the peninsula. A city of maritime tradition, it has a century-old touristic vocation. It is home to two treasures that are UNESCO World Heritage Sites: a part of the Way of Saint James and the Cave of Altamira. Its Prehistory and Archaeology Museum houses one of the most valuable Palaeolithic collections in Europe and the Maritime Museum of Cantabria is one of the most comprehensive museums in Spain dedicated to the sea. Its beaches with peaceful waters, protected from the wind, offer one of the most beautiful sea fronts with a succession of Belle Époque buildings.

Now the third largest city in the Principality of Asturias, Aviles has managed to retain all its charm. Its old town, declared a Historic-Artistic Site, contains architectural marvels such as the pedestrianised streets Calle Galiana and Calle Rivero, the Plaza de España and its town hall, and the Church of Sabugo, dating from the 13th century. Between palaces – including the very beautiful Valdecarzana and Camposagrado palaces –, shady arcades, fountains and other historical monuments, fall in love with this city and its unique heritage.

La Coruña stands on a peninsula in north-west Spain.  As you enter the harbour, you can see the imposing Castillo de San Antón, which houses archaeological collections from Galicia. In the old town, you’ll travel back in time as you meander through the streets from the medieval church of Santiago to the contemporary Domus building, a museum dedicated to human biology and psychology. Brightly coloured tramways connect to the waterfront, on one side, Riazor beach, and on the other, the Hercules tower: this lighthouse overlooking the Atlantic, is a UNESCO World Heritage site, listed for its history dating back to Antiquity.

Nestling on the Atlantic coast, in the south of Galicia, the former fishing port of Vigo is now the region’s largest municipality. Its old town, more commonly known as O Berbés, will unveil its many historical monuments and the unusual architectural style of its homes. Off the coast, the Cíes Islands, declared a Nature Reserve and located in the Atlantic Islands of Galicia National Park, offer truly splendid landscapes and exceptional biodiversity. Further north, make sure you visit Santiago de Compostela, which welcomes many pilgrims from all over the world every year. Designated a UNESCO World Heritage Site, its historical centre has significant architectural heritage.

Located at the mouth of the Douro River, the port of Leixões lies less than 10 kilometres from Porto. A UNESCO World Heritage Site, the historic centre of Porto is worth a visit for its famous Ribeira district, the metallic silhouette of the Dom-Luis bridge looming over its ancient houses, its richly decorated Baroque churches and its national Soares dos Reis museum. The São Bento station is also interesting for its typically Portuguese decoration, using Azulejos, blue square ceramic tiles decorated with geometric patterns or figurative scenes.

Portugal’s capital city located on the banks of the Tagus, only a few kilometres from the Atlantic coast, is a city of exceptionally rich cultural diversity. At the mouth of the river harbour, impose two UNESCO World Heritage monuments, Jeronimos monastery and Belem tower. The Alfama hillside is also worth visiting: known for its fado bars and its Moorish streets, this district is the oldest one of the city and one of the most typical. Not far from there, Chiado’s elegant streets are home to big fashion labels and are an invitation to a bit of of luxury shopping.
