The Palacio de la Magdalena was built between 1909 and 1911, by popular subscription, to house the Spanish Royal Family. Built by the architects Javier González Riancho and Gonzalo Bringas Vega, is located in the place where the old Fort of San Salvador de Hano was, which protected the entrance to the bay.
The design and construction of the palace were overseen by architects Javier González de Riancho and Gonzalo Bringas Vega, with construction completed in 1912. King Alfonso XIII and his family first arrived at the Palacio de la Magdalena on August 4, 1913, and returned annually to summer at the palace through 1930. The royal family used the palace as a base for numerous recreational and sporting activities, and the king sometimes also held government meetings at the property. The annual trips ended with the proclamation of the Second Spanish Republic in 1931.
Beginning in 1932, the palace was used to host summer courses through the Menéndez Pelayo International University. In 1977 the Count of Barcelona sold the palace and the peninsula back to the city of Santander for 150 million pesetas. The palace was declared an historical monument in 1982 and renovated between 1993 and 1995. It is the most visited place in the city of Santander and continues to be used as a conference and meeting hall to the present day.
The building has an eclectic style, combining English, French, and regional architectural styles. It has two points of entry, a north entrance with a Porte-cochère for carriages, and a second entrance to the south which was designed as the main entrance. The building is covered with stone masonry slate. The highlight of the interior is the reception rooms, which hold paintings of interest by artists such as Luis Benedito, Joaquín Sorolla y Bastida, and Fernando Alvarez Sotomayor.
The stables were designed by Javier González de Riancho. They emulate a medieval English village with sharp roofs of steep slopes and wooden tiles. After summer courses were started, the stables were converted to student dormitories.
Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
