The ramparts, 900m long and 13m high, and the dry moat that surround the Crusader city were constructed by King Louis IX of France (St Louis), better known for building Ste-Chapelle in Paris. To get an overview of the site, head up the slope from the minaret by the harbour; a path leads to the remains (three rounded apses) of a 13th-century Crusader church , built over the site of Caesar’s temple and destroyed by the Muslims in 1291.
The Crusader city, situated between the park's northern entrance and the harbour, is accessible whenever the site is open.
