When the lighthouse was in operation on Spy Point (decommissioned in the 1950's) the light was visible between eight and twelve miles. It was built in 1911, replacing the previous lighthouse built in 1904.
When walking east along the coastal path, from Polperro, there is another narrow path leading to steps that lead to the lighthouse. Great views out to sea, of course. There is a safely rail around the building to, hopefully, stop visitors falling 140 feet and splashing into the sea.
