Formerly known as Portus Blendium in Roman times, final destination of the Roman road that joined the plains with the Northern coast, this quiet seaside town located at the natural outlet of the confluence of the Rivers Saja and Besaya was used as a natural pier and starting-out port for the minerals extracted from the old Reocín mines.

The la Rabia beach, on the left-bank of the river of the same name, is often confused with the Oyambre beach, as both are part of the Oyambre natural park.
Santillana del Mar is also known as the “Town of three lies” because it is not saintly (Santi in Spanish), nor flat (llana), nor is it sea-side (del Mar).
