The first radio signal across the ocean
When in Cornwall it may be interesting to visit the place where, for the first time, a radio wave was sent across the Atlantic and received in Canada.
Nowadays there is just a monument there to mark the place, but for several years the premises of the very first radio station, created by Guglielmo Marconi, were there.
In order to reach it you can go by bus (from Helston) or by car to Poldhu Cove, and then walk the coastal path along beautiful cliffs, until you reach the monument.
There is not much to see or to do, excepted enjoying the beauty of the sea coast, and reading the inscription that describes the historic event.
