Italian archaeologists excavating the Phrygian city of Hierapolis in southwestern Turkey uncovered the remains of Pluto’s Gate, a site considered an entrance into the underworld in the Greco-Roman period. The apostle Philip preached and died at Hierapolis, a thriving Roman city that became an important Christian center.

Shrouded in misty poisonous vapors, Pluto’s Gate, or the Plutonium, was a cave entrance sacred to Pluto, the Roman god of the underworld. According to the first-century geographer Strabo, the site was home to rituals in which any animals entering the enclosure “meet with sudden death.” Hierapolis archaeologist Francesco D’Andria reconstructed the route of the area’s thermal spring to discover Pluto’s Gate, which was destroyed by Christians in the sixth century. The Plutonium’s infamous mystique is not just the stuff of legend; during the excavation, several birds were killed by carbon dioxide emissions as they approached the Plutonium cave’s entrance.

This is not the first astounding discovery at D’Andria’s excavation at Hierapolis, located next to the often-visited hot springs and travertines at the World Heritage Site of Pamukkale. According to the apocryphal Acts of Philip, the apostle Philip preached and converted many Hierapolis residents, yet he was martyred there nonetheless. An octagonal church was built in Hierapolis to memorialize the saint, and a sixth-century bread stamp depicts Philip standing at the very site. The publication of D’Andria’s article “Conversion, Crucifixion and Celebration” in the July/August 2011 issue of Biblical Archaeology Review was followed by the discovery of a small church that D’Andria believes to be the tomb of St. Philip.

Hierapolis’s gateway to hell was an important sacred space in the city. The first-century traveler Strabo described its deadly properties:

The Plutonium, below a small brow of the mountainous country that lies above it, is an opening of only moderate size, large enough to admit a man, but it reaches a considerable depth, and it is enclosed by a quadrilateral handrail, about half a plethrum in circumference, and this space is full of a vapour so misty and dense that one can scarcely see the ground. Now to those who approach the handrail anywhere round the enclosure the air is harmless, since the outside is free from that vapor in calm weather, for the vapor then stays inside the enclosure, but any animal that passes inside meets instant death. At any rate, bulls that are led into it fall and are dragged out dead; and I threw in sparrows and they immediately breathed their last and fell. But the Galli, who are eunuchs, pass inside with such impunity that they even approach the opening, bend over it, and descend into it to a certain depth, though they hold their breath as much as they can (for I could see in their countenances an indication of a kind of suffocating attack, as it were)—whether this immunity belongs to all who are maimed in this way or only to those round the temple, or whether it is because of divine providence, as would be likely in the case of divine obsessions, or whether it is, the result of certain physical powers that are antidotes against the vapor (Strabo, Geography 13.4.14, trans. by Horace Leonard Jones).
