An important Phoenician port, a fortified city located along the Acre-Antiochus highway. Served as a fortress during the Crusader era. In those times Achziv was called Castel Humbert, ruins of which can still be seen. In 1271 it was conquered by the Mamluk Sultan Baibars. Most of the remains you see today are from the abandoned Arab village of Az-Ziv.
Today Achziv National Park is noted as one of northern Israel’s most popular beaches, located 5 km north of Nahariyya.
Achziv beach features a rocky shoreline, inlets and lagoons, and a natural and an artificial sea-water pool- a deep one as well as a shallow one suitable for children. There are also broad lawns and antiquities. In short, everything you need to enjoy hours of Israeli sunshine. Achziv is special for the sea anemones, sea urchins and small octopi that can often be seen hiding among the rocks, and in July and August, the sea turtles that lay eggs on the beach. Small islands, where seagulls nest in summer, are nature reserves in their own right, remnants of once-landlocked calcareous limestone (kurkar) ridges. Remains can also be seen of the ancient settlement of Achziv, mentioned in the Bible as a city of the tribe of Asher, and an important Jewish city in Talmudic times. A mainstay of Achziv’s ancient economy was the production of purple dye from special snails collected on the beach.
Remnants of ancient Achziv, now known as Tel Achziv, are located on a sandstone mound between two streams, Kziv on the north and Shaal on the south, close to the border with Lebanon. An ancient port was located on the coast, and another secondary port is located 700 m to the south. Archeological excavations have revealed that a walled city existed at the location from the Middle Bronze period. History of Achziv goes back to the Chalcolithic period (4500-3200 BC).
