The only monument of real interest in Al-Mina is the Lion Tower, a miniature fortress at the eastern end of the harbour. Named after the bas-relief lions that used to line the facade, the building dates from the end of the 15th century and was probably built by Mamluk sultan Qaitbey to protect the coastline against attack from the Ottomans.
It's an exceptional example of Mamluk military architecture, with a striking black-and-white striped portico. The whole of the ground floor is one vast chamber with traces of paintings and armorial carvings. The upper floor has eight rooms opening onto a central hall and the roof terrace has great views. Lion Tower is separated from Al-Mina proper by old railway sidings. The only other remains of ancient Tripoli are a few dejected-looking Roman columns in a park near the seafront and the remains of an Ottoman khan (caravanserai) that has been converted into apartments.
