Renfrew is a town, located 6 miles (9.7 km) west of Glasgow in the West Central Lowlands of Scotland. Traditionally, Renfrew is the county town of Renfrewshire (also known as the County of Renfrew), a unit of local government used until the reorganisation of 1975. The name Renfrewshire survives in local government in the names of the modern council areas of Renfrewshire and East Renfrewshire. In 1164, Somerled, Lord of the Isles sailed to Renfrew and attacked Clan Stewart, known as the Battle of Renfrew. The outcome was a defeat of the Lord of the Isles and the death of Somerled. The town is located at the confluence of the River Clyde and the River Cart. A passenger ferry crosses the Clyde to Yoker and a bascule bridge crosses the Cart to Inchinnan and Glasgow International Airport.
