River Nethan The River Nethan is a river which flows between Glenbuck in East Ayrshire and Crossford, South Lanarkshire where it feeds into the River Clyde, with the town of Lesmahagow and surrounding villages sitting on the river course. The area of woodland surrounding the River Nethan at Crossford and Auchenheath has been declared a site of special scientific interest and forms a part of the Clyde Valley Woodlands National Nature Reserve as Nethan Gorge. Craignethan Castle, a 16th-century fortification, overlooks the river.
Renfrew Castle Renfrew Castle was situated at the royal burgh of Renfrew, Scotland, which is near the confluence of the River Clyde and the White Cart Water. The original 12th-century castle was built by Walter fitz Alan, High Steward of Scotland, 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.
