This is the point from which Nelson reportedly used to check the ocean for ships coming from the south; he was watching for Spanish and French ships, which might have meant trouble, as well as for other British ships.
Back then, the old main road around the island, the "Lower Round Road", used to follow the coastline of Nevis, even going around south of Saddle Hill, but that strip of land has partly been lost to marine erosion.
