This is St. Peter's house in Capharnaum. It was rediscovered in 1968 under the foundations of the octagonal church some 30 meters south of the synagogue. To quote Matthew: Jesus said to them: But who do you say I am? Simon Peter answered and said: You are Christ, the Son of the living God. And Jesus answering, said to him: Blessed are you, Simon son of Jona, because flesh and blood have not revealed this to you, but my Father who is in heaven. And I say to you: That you are Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it.

The the foundations of St. Peters house are chest high and still stand. It is the inter rock circle. The rocks still stand, go figure! They looked pretty solid to me.
