Torre de Ca sa Blanca Dona, Defensive tower in Santa Eulària des Riu, Spain.
Torre de Ca sa Blanca Dona is a stone defensive tower located near the coast of Santa Eulària des Riu. The structure displays typical characteristics of Balearic fortifications, with its solid construction designed to overlook the surrounding waters and land.
The tower was built during a period when pirates and raiders frequently threatened the Balearic coasts. It gained official cultural heritage protection status in 1993 under Spanish law.
The tower was part of a network that protected coastal communities from raids, reflecting how island residents organized their defense. Walking around it today, you can see the practical design choices they made to watch over the sea and surrounding land.
The tower is accessible from local footpaths and located near the village of Santa Eulària des Riu. Wear sturdy shoes when visiting, as the surrounding terrain can be uneven and the site sits close to the coastal landscape.
The tower is part of a wider defensive network that stretched across multiple Balearic islands and was maintained by residents over centuries. This decentralized approach to coastal protection was particularly characteristic of how island communities organized their security.
