==Instances== At Eleusis, the ploutonion was near the north entrance to the sacred district (temenos). It was built by Peisistratos in the 6th century BC and rebuilt two centuries later, when the Eleusinian Mysteries were at the height of their influence. The cave was the traditional site of the birth of the Divine Child Ploutos.
