El municipio de Santa Eulària debe su nombre al río, el único que existe en Baleares. Aunque actualmente apenas baja agua, durante muchos años su caudal fue importante y se convirtió en la principal fuente de vida para sus habitantes.
The river is born in the region of Besora, Sant Antoni, it runs for 18 km, going through Santa Gertrudis until it reaches Santa Eulària. Many roads and paths go over it, and two main bridges: the Puente Viejo (old bridge) and the Puente Nuevo (new bridge). The water from the river was redirected into three main ditches that distributed the water to mills and gardens of the area. This allowed gardeners to grow several kinds of crops.
In the entrance of the town of Santa Eulària, there is a peasant house, Molí de Dalt or Can Planetes. It has an Andalusian-origin water mill (10th century) that was active until 1950. Nowadays, it is the River’s Interpretation Center. This is the starting point of a route that will make you understand the close relationship between the river and the town.
The first flour mill in Can Planetes was of Andalusian origin (10th century). Years later, it was replaced by a horizontal wheel, and in the 18th century, by a vertical wheel. It has been restored following the original plans and now it can be seen at work. It is one of the four mills that watered the gardens of the area (Molí de Dalt, Molí de Mig, Molí de Can Marge, and Molí de Baix). Just as the houses, they were built close to the river.
A trail of information panels explains the river’s history and its importance to the town’s inhabitants. The canal system, ditches, gardens, and mills are still an important part of the valley, as visitors will see from the house’s lookout. “[…] this valley, of sweet and fine beauty, in which all essence and quintessence on the island seem to come together […]”, Josep Pla wrote in the Mallorca guide Memoria Ibiza y Formentera (1970).
