Israel Trip - Anunciation Basilica

One of the first significant Christian church that we visited in Israel was the Anunciation Basilica. This is where Mary (Jesus' Mother) received the message from the Angel that she will bear the son of God. Our guide did not narrate how modern day people figured this location as the site of Mary's Anunciation. So that made me wonder if this really happened here. And I will repeat this theme of questioning in the other Holy sites that we visited.
Inside the church compound were images from different countries of their version of the Anunciation of Mary. The church itself was not very ancient looking or spectacularly grand. Under the church compound was some dug up ancient caves. Perhaps that is where Mary lived. I was not sure.
