Renfrew Castle

Renfrew Castle was situated at the royal burgh of Renfrew, Scotland, which is near the confluence of the River Clyde and the River Cart. The original 12th-century castle was built by Walter fitz Alan, upon a river islet known as the King's Inch. This was replaced in the 13th century with a new castle by the road to the Clyde ferry, which became a royal castle under King Robert II. In the 15th century, the King's Inch site was rebuilt as Inch Castle by Sir John Ross. Both castles were demolished in the 18th century and nothing remains above ground at either site.
