The sea castle of Sidon is actually a fortress which was erected by the Crusaders in the early 13th century. It is located on a small island which is linked to the mainland through a causeway and was once the site of a temple to the god Melkart. Even though the castle was destroyed by the Mamluks it was rebuilt once again in the 17th century the ruins of which can still be visited today. Once you climb to the top you can get a pretty good view of the port and the older parts of the city. At present, Sidon only comprises of two towers that are connected with each other by a wall. In the outer one, Roman columns were installed as reinforcements, but it is the west tower which has stood the test of time the best. Even though little remains of the decorations that were part of the ramparts in days of yore, there is still a lot to see in the ruins. During favorable weather conditions, you can also see a number of rock granite columns lying on the sea floor which surrounds the castle. All in all, the castle is worth a visit if you are an avid historian or a tourist.
