Wheal Prosper was a tin mine in Cornwall, England, a short distance from the hamlet of Rinsey and about 2.5 miles (4 km) west of Porthleven. The ruined engine house remains, overlooking Mount's Bay near Rinsey Head. The site is a Scheduled Monument, [1] and the engine house is a Grade II listed building. [2]
The mine opened circa 1860 to exploit the Porthclew lode; it closed in 1866. It was acquired by the National Trust in 1969 and preserved. [2] [3]
The building housed an engine of cylinder diameter 30 inches, to pump water from the mine. It has three storeys; it is built of killas rubble, with dressed granite quoins, and the chimney has an upper section of brick. [1] [2]
