Tripoli, In Arabic: Ṭarābulus, city and port, northwestern Lebanon. It lies on the Mediterranean coast at the mouth of the Abu Ali River, 50 miles (80 km) north-northeast of Beirut. Tripoli is the ancient city that dates back to the Phoenician era, and is one of Lebanon's oldest cities, alongside Byblos, Tyre and Sidon. Forty-five buildings in the city, many dating from the 14th century, have been registered as historical sites. Twelve mosques from Mamluke and Ottoman times have survived. Secular buildings include the “hammam” or the bathing-house, the souks, and the “khans”, that form an agglomeration of various trades

Citadel Saint Gilles (Qal'at Sinjil)

Overlooking Tripoli city is the imposing Citadel of Tripoli known as Qal’at Sinjil (Saint Gilles), which has been renovated and changed many times during its history. Today the castle’s main features are an octagonal Fatimid construction converted to a church by the Crusaders, some Crusader structures of the 12th-13th centuries, a number of 14th century Mamluke additions, as well as additions made by the Ottomans in the 16th century. The present state of this huge fortress (140 meters long and 70 meters wide) is largely the result of extensive restoration work by Mustafa Barbar Agha, governor of Tripoli at the beginning of the 19th century.
