The Mseilha Fort (Arabic: قلعة المسيلحة‎) also known as "Puy du Connétable" is a medieval fortification situated north of the city of Batroun in Lebanon. The current fort was built by Emir Fakhreddine II in the 17th century to guard the route from Tripoli to Beirut. The fort is built on a long, narrow limestone rock near the Nahr el-Jawz River. Its walls are constructed with small sandstone blocks quarried from the nearby coast and built onto the edge of the limestone rock. The thickness of the walls ranges from 1.5 to 2 meters (4 to 6.5 feet).
