The site of the spring is now covered over, though it emanates from under the roadway and flows out onto the adjacent beach. The well was traditionally famous for the healing virtue of its waters, and it remained a favourite source of drinking water until the end of the 19th century; the spring was latterly covered in and a pump-standard provided for the convenience of local residents. This was removed when piped water supply became available.


William Milner, a philanthropist who resided in Port Erin until his death in 1874 erected a stone nearby, inscribed 'St Catherine's Well - Keep me clear'. Since 1923 this has been secured on top of a low wall above the well site.
