The remains of a possible water storage pit or a swimming pool. If it was used for storing water, it may have been for the mill that was at Cwm Elan stables.
There is a water leat that runs from Nant Methan near Cwm Elan Mine, the leat runs through a stone culvert and runs for a distance to the pit. There are some lead pipes in situ at the site.
