Tripoli ( / ALA-LC: Ṭarābulus; Lebanese Arabic: Ṭrāblos; / Tripolis; ) is the largest city in northern Lebanon and the second-largest city in the country. Situated north of the capital Beirut, it is the capital of the North Governorate and the Tripoli District. Tripoli overlooks the eastern Mediterranean Sea, and it is the easternmost seaport in Lebanon. It holds offshore a string of four small islands, the only surviving islands of Lebanon. The largest of these islands, the Island of Palm Trees, was declared a protected reserve by UNESCO in 1992 for its rich ecosystem of trees, green sea turtles, and exotic birds.
