Tripoli has a population of 1.69 million. The city is located in the northwest of the country on the edge of the desert, on a point of rocky land projecting into the Mediterranean Sea and forming a bay. Tripoli was founded in the 7th century BC by the Phoenicians, who named it Oea.
Tripoli is the largest city, the principal sea port, and the largest commercial and manufacturing centre in Libya. It is also the site of Al-Fateh University. Due to the city's long history, there are many sites of archaeological significance in Tripoli. The climate is typical Mediterranean, with hot, dry summers, cool winters and some modest rainfall.
"Tripoli" may also refer to a "Sha'biyah" (top-level administrative division in the current Libyan system).
