Ashkelon National Park (Hebrew: גן לאומי אשקלון‎) is an Israeli national park along the shore of the Mediterranean Sea southwest of the city of Ashkelon. The national park is situated in the heart of ancient Ashkelon. It is surrounded by a wall built in the mid-12th century by the Fatimid Caliphate. The wall was originally 2,200 meters in length, 50 meters in width and 15 meters in height. The remains of the wall are located in the eastern and southern parts of the national park.
