The tomb was perhaps located in the sacred city of Antinoopolis, but this is not certain.
It might have also been located in Rome, at Hadrian's Mausoleum, or at the Villa of Tibur.
No one knows, the tomb, and the body of Antinous is lost.
Flamen Antonius Subia says:
"We must search for his remains and for his final resting place within our selves. The Entombment of Antinous, like his return to Bithynia is a final triumph of the Body of Antinous, it is the final part of the earthly journey, and the occasion of the most solemn ceremonies of dedication. We are the Tomb of Antinous, and the Entombment is our moment of impregnation."
