Although this tradition was first recorded in the 1700s, the powers of the Maen-Du Well became so famous that women continued to drop pins there well into the 20 th- century.
Er mai yn yr 1700au y cofnodwyd y traddodiad hwn gyntaf, daeth pwerau Ffynnon Maen Du mor enwog nes i fenywod barhau i ollwng piniau yno ymhell i'r 20 fed ganrif.
