As early as the 6th century, the mouth of the Salaca was a Liv settlement known as Saletsa. In 1226 Bishop Albert of Riga built a fortress Salis or Salismünde here, but by the 18th century, it had been completely destroyed by war. Even into the 19th century, the village remained remote and poor, until the construction of a port and shipping industry in the 1870s vitalized the village. A harbor and pier were built, and the mouth of the Salaca was dredged to allow greater shipping access. For a short time Salacgrīva was northern Vidzeme's chief port, handling exports such as grain, flax, and wood for transportation to either Riga or Pärnu. Over 200 ships a year called port at Salacgrīva.
