The Holy House of Loreto

According to the New Testament, Jesus was raised by Mary and Joseph in a small town called Nazareth, near Jerusalem. Joseph was a carpenter, and their house was humble. Three centuries after the life of Jesus, the newly-converted Emperor Constantine built a basilica over the humble brick house believed to have sheltered the Holy Family.
According to Catholic tradition, the Holy House came under threat during the turmoil of the Crusades, so in 1291, angels miraculously translated the house from its original location to a site in modern-day Croatia. An empty space was left in Nazareth and a small house suddenly appeared in a field in Croatia. The bewildered parish priest, brought to the scene by shepherds who discovered it, had a vision in which the Virgin Mary revealed it was her former house.
On December 10, 1294, the house was again moved by angels because of the Muslim invasion of Albania. It landed first in Recanti, Italy, but was shortly thereafter moved for a third time to its present location in Loreto.
The Holy House of Loreto, or Santa Casa di Loreto in Italian, has been venerated by pilgrims great and small, including many popes and saints, and numerous miracles and healings have been reported. Scientists are said to have confirmed the materials to be the same as those found in Nazareth and the house lacks normal foundations.

I was not able to take pictures inside of the marble shrine of the actual Holy House, but if  you are interested in seeing what it looked like, I'm sure if you google it, you will find it :)
