This time it's the site of a dance floor mentioned in the New Testament book of Mark, where King Herod sentenced prophet John the Baptist to death.
Győző Vörös, director of Machaerus Excavations and Surveys at the Dead Sea, says a courtyard first discovered in 1980 at a site in Machaerus, Jordan, also has an apse - a semi-circular enclave where ancient kings and queens sat on their thrones.
It's only recently been discovered, suggesting the courtyard was where - according to the gospels - his wife Herodias' daughter Salome danced before Herod's party guests, and then - prompted by her mother - asked for John's head as a reward.
Herodias was no fan of John, the latter having criticised the pair for divorcing their previous partners and remarrying. Herod didn't want John dead, but did it because he had promised Salome anything she wanted as a reward for the dance.
"I think it is historically probable that this excavation has brought the 'dance floor' of Salome to light," Morten Hørning Jensen of the Norwegian School of Theology told Live Science.
Others suggested Vörös, who makes the claim in a new book, might have jumped the gun - one noting the apse is much smaller than that which housed the throne of his father, also called Herod.
According to the Bible, John the Baptist foretold of Jesus' arrival and was the one who baptised him. Jesus didn't start his own ministry until after John had been arrested.
Last year a British archaeologist claimed to have found Jesus' childhood home in Nazareth, Israel, and another from Israel said he'd proved two nails found in a tomb linked to the alleged son of God had indeed been used in a crucifixion.
