The Ploutonion at Hierapolis (Ancient Greek: Πλουτωνειον, lit "Place of Pluto"; Latin: Plutonium) or Pluto's Gate was a ploutonion (a religious site dedicated to the god Pluto) (another name for the god Hades) in the ancient city of Hierapolis near Pamukkale in modern Turkey's Denizli Province. The site was discovered in 1965 by Italian archaeologists, who published reports on their excavations throughout the decade. In 2013, it was further explored by Italian archaeologists led by Francesco D'Andria, a professor of archaeology at the University of Salento.
