This is probably the most famous well in the area and is still much visited. Rags are still hung from the surrounding trees and bushes. Water runs from the simple circular stone-lined well to the nearby ruined chapel where it fills a simple baptistry before being piped by a leat to the causewayhead Reservoir which feeds the Morrab Garden fountain in Penzance. The chapel measures about 24 feet by 16 feet, is roofless and has an altar at the opposite end to the baptistry. There are simple granite seats down the sides.
Wild roses grow on the chapel walls making it a beautiful sight in summer.
There are many stories of cures that have taken place here, the most quoted being that of John Trelill, a cripple for 16 years, who washed in the water and was cured, early in the 17th century. A new path has recently been made to the well avoiding muddy ground, and the chapel and well are both kept in good condition and are well worth visiting. Most easily reached along the coast path from Portheras Cove. Where the path drops down into a small valley directly north of Morvah village there is, in the corner of the adjacent field, an ugly concrete shed which covers a derelict pump which once pumped away the water from this well. The ground all around is boggy and many shaped stones are lying around under the vegetation.
