As other ancient sites in Cyrenaica, Tulmaytha has a beautiful setting, making the most out of the plains meeting with the sea. This site has, however, most its potentials still underground. Tulmaytha was established by Ptolemais in 4th century BC, and its importance continued during the Roman period, but with the arrival of the Arabs in the first half of the 7th century AD, it fell into decline.
There are enough things excavated here to make a visit to Tulmaytha worth while. The best thing here is the basilica from 5th century AD. Other structures excavated, include a Hellenistic palace, the forum, statues and plenty of fountains. A visit to the museum is nice, and it has a good collection of everyday articles.
