The house was cut into a limestone hillside and incorporates parts of a natural cave, so many features – such as a staircase – still survive.
Prof Dark started his research in 2006 at the site which he describes as “almost forgotten” by historians. He published an article in 2015 based on his initial findings as he suggested the site was the childhood home of Jesus.
Fresh analysis has now dated the site back to the 1st century which helps to add weight to his claims.
In his book, The Sisters of Nazareth convent: A Roman-period, Byzantine and Crusader site in central Nazareth, he claims the style of the house suggests it was owned by Joseph. Joseph is commonly known as a carpenter, but in the original Greek texts, he is described as a tekton.
It is profession which could also be a stonemason or builder, which would match up with the two storey house being hewn into the rock.
Prof Dark also found fragments of pottery at the site which were commonly used by Jewish families of the era. His fieldwork also suggested a cave church built directly adjacent to the house in the 4th cenutry.
And this is around the time Christianity was adopted as the state religion of the Roman Empire under emperor Constantine.
The further study unearthed a 5th-century church built over both the house and the cave church. It would have been the largest church in Nazareth and was an elaborately decorated cathedral with marble and mosaics.
This matches a 7th century description of the large Byzantine church that was said to have stood on the site of Jesus’s home
Prof Dark explains the fact the church was even bigger than the nearby Church of the Annunciation shows the cave home’s potential significance. The Church of the Annunciation is where it is said the Archangel Gabriel visited Mary with news that she would give birth to the Son of God.
While he admits there is no concrete proof the house was where Jesus lived, he says there never good evidence for any archeological site to categorically make that claim.
“On the other hand, all the reasons to doubt that it might possibly have been, have gone — this is exciting stuff,” he said.
He claims there is “absolutely no reason” why the location of Jesus’ home could not have been passed down from the 1st to 4th century. The expert said based on “oral tradition” this would explain the erection of the church and subsequent cathedral.
Prof Dark told MailOnline: “This suggests that displaying a house in this way was something really unusual and significant.
“It also begs the question of how did the church builders know these were first-century houses unless some tradition about them remained?
