The Palace on the Sea
When Alfonso XIII made Santander Spain's summer capital
📱 1 to 10 phones · 1 team per phone · Independent codes
In 1912, the people of Santander offered their king a palace so he'd spend his summers with them. The gamble paid off: all Spanish aristocracy followed, and the city became the Biarritz of the Cantabrian coast.
A palace offered to a king, a beach offered to an era
The Magdalena Peninsula is Santander's jewel. Its eclectic palace, built in 1912 by public subscription for King Alfonso XIII, dominates the bay from a wave-battered promontory. Around it, the Sardinero quarter unfolds its Belle Époque villas, its Gran Casino and fine-sand beaches. This game immerses you in Santander's golden age, when the king bathed at El Sardinero and Madrid's aristocracy competed in splendour.

« "The king wanted Biarritz. The people of Santander gave him better: a palace with its feet in the Atlantic." »— — On the terrace of the Palacio de la Magdalena, facing the island of Mouro
The Cantabrian Belle Époque: when Santander rivalled Biarritz
In the late 19th century, sea bathing became fashionable among European aristocracies. Santander, with its magnificent bay and Sardinero beaches, attracted the first Madrid summer visitors. In 1899, the Gran Casino del Sardinero opened its doors, and turreted villas began springing up along the coast.
The masterstroke came in 1908, when the city council decided to offer a palace to King Alfonso XIII. Architect Javier González Riancho designed an eclectic building blending English and French influences, perched on the Magdalena Peninsula. The king stayed there every summer from 1913 to 1930. The entire court followed.
The proclamation of the Republic in 1931 ended the royal summers. The palace became successively a hospital, a prison, a summer university. Restored, it is today the symbol of this golden parenthesis. El Sardinero retains its villas, its casino and that Belle Époque atmosphere that time hasn't quite erased.
