It is a small and charming dock on the banks of the Suances estuary, used since ancient times and its location and surroundings were described in the work "La Puchera" by Jose Mª de Pereda.
When the current port did not exist, the ships docked past Punta del Hornillo, at the Cantos dock and from there, the sailors and fishermen went up to the Cuba de Abajo neighbourhood where most of them lived despite not being located on the riverbank. At that time, the sailors lived far from the coast for fear of raids and attacks, so it was not until more recently when a fishermen's neighbourhood began to be built in Suances near the coast. In this place it is still common today to see its neighbours looking out from the viewing points daily checking the state of the sea, having an unbeatable view of the departure and entry of the ships through the San Martín de la Arena estuary.
