Santillana del MarOutdoor Escape Game & Treasure Hunt

From Monastery to Medieval Capital

The history of Santillana del Mar begins in the 8th century with a monastery. Monks brought the relics of Saint Juliana of Bithynia to this location. This religious site developed, and by the 12th century, it became the Collegiate Church of Santa Juliana, drawing pilgrims and shaping the town around it. The town's name is a contraction of "Sancta Illana," referring to Saint Juliana.

By the Middle Ages, Santillana del Mar had become a religious and economic center, also serving as a stop on the northern route of the Camino de Santiago. In 1209, King Alfonso VIII granted Santillana its municipal charter, establishing it as the capital of the Asturias of Santillana. The 14th and 15th centuries saw noble families construct defensive towers and manor houses, such as the Torre del Merino and Torre de Don Borja, which defined the town's medieval layout. The town's prosperity continued, with many buildings in the historic center dating from the 14th to 18th centuries. Much of the wealth that shaped the town's 18th-century architecture came from inhabitants who had emigrated to the Americas and returned with their fortunes.

Prehistoric Roots and Architectural Preservation

Beyond its medieval core, Santillana del Mar's history extends back millennia. The area has been inhabited since prehistory, with evidence found in the nearby Altamira Cave. Discovered in 1868, this UNESCO World Heritage Site contains some of the world's oldest prehistoric artwork, primarily of bison, created by the Magdalenian people over 14,000 years ago. While the original cave is closed for preservation, the Altamira Museum offers a replica, the Neocave.

The town's historic center was declared a Historic-Artistic Site in 1889. Restoration efforts began in 1927 to preserve its architectural blend of Romanesque, Gothic, and Renaissance styles. Today, Santillana del Mar's stone streets and stone buildings present a continuous story from prehistoric times to the present.

• —Colegiata de Santa Juliana — This Romanesque church from the 12th century is the town's spiritual center, built on the site of an earlier monastery. The cloister features carved capitals depicting floral, geometric, and figurative motifs. The main altarpiece combines late Gothic and Plateresque styles from the late 15th and early 16th centuries.
• —Torre del Merino — A 14th-century defensive tower that served as the residence and office of the merino, a royal official who administered justice. Its stone construction, small defensive windows, and crenellated top show medieval power structures.
• —Torre de Don Borja — This 14th or 15th-century Gothic tower house illustrates the influence of the noble families who shaped Santillana del Mar. It now functions as a cultural center, hosting art exhibitions.
• —Plaza de Ramón Pelayo — This triangular square, formerly Plaza Mayor, has been the town's central gathering place for centuries. It is bordered by buildings such as the Town Hall, the Casa del Águila y la Parra, and the Parador de Turismo Gil Blas, many displaying coats of arms.
• —Museo de Altamira (Neocave) — A short distance from the town, this museum houses the Neocave, a replica of the Altamira Cave. It allows visitors to view the Palaeolithic cave paintings, primarily of bison, as the original cave is closed to the public.
• —Calle de Santo Domingo & Calle de Juan Infante — These cobbled streets feature traditional Cantabrian houses, many with wooden balconies, and palaces with carved coats of arms, reflecting the town's medieval and Renaissance architecture.
