Military Architecture
The Military Architecture.  
    Castle of San Vicente de la Barquera   Also between the 13th and 15th centuries, a strong development of the military architecture took place in Cantabria. On the one hand, there are castles, which are generally public, with a regular construction and somewhat complex in structure although of small size. In spite of being in the coastal villages, as is the case of the castle of San Vicente de la Barquera or San Felipe, now disappeared, in Santander, these castles were designed with a defensive purpose in land attacks. On the other hand, the tower appears as the most typical defensive device in Cantabria. Being owned by lords, these towers were built due to the struggles between the local noble families. Those in the rural area may only have one defensive body or be surrounded by a fence and have a moat, as happens in the towers of Estrada, Cabanzón, etc., turning in the 14th century into the more horizontal tower-houses, with more bay windows and a less marked military character. Among these are the Don Borja and El Merino towers in Santillana del Mar.
