God protects and governs all things which he has made
By his providence God protects and governs all things which he has made, “reaching mightily from one end of the earth to the other, and ordering all things well”. For “all are open and laid bare to his eyes”, even those things which are yet to come into existence through the free action of creatures. (Cathechism 302)
Did Angels take Mary's Holy House from Nazareth to Loreto?
The Holy House of Our Lady, where the Archangel Gabriel announced to her the Incarnation, took off from its foundations in Nazareth on May 9, 1291 and reappear the next day 2,000 miles away in the town of Tersatto (now Trsat), Croatia, and arrived in Loreto, Italy, during the night between December 9-10, 1294

Detractors
Detractors claim that a wealthy family dismantled the house in Nazareth, transported it, and rebuilt it in Loreto. Today, historians say that this was a fabricated story to falsify aristocratic accreditations, a fraud typical of that time.
Evidence
St Catherine Emmerich reported her recurring vision of the Holy House carried over the sea by seven angels. Historical, scientific, and archeological evidence attests that there is no other logical explanation.
Pontifical Sanctuary
According to the Pontifical Sanctuary of the Holy House of Loreto, both the authoritative tradition and archaeological and philological studies agree that this transportation was possible thanks to the help of "Heaven", an "angelic" intervention.
God protects the Holy House of Mary
The witness of Scripture is unanimous that the solicitude of divine providence is concrete and immediate; God cares for all, from the least things to the great events of the world and its history. The sacred books powerfully affirm God’s absolute sovereignty over the course of events: “Our God is in the heavens; he does whatever he pleases.” And so it is with Christ, “who opens and no one shall shut, who shuts and no one opens”. As the book of Proverbs states: “Many are the plans in the mind of a man, but it is the purpose of the LORD that will be established.
And so we see the Holy Spirit, the principal author of Sacred Scripture, often attributing actions to God without mentioning any secondary causes. This is not a “primitive mode of speech”, but a profound way of recalling God’s primacy and absolute Lordship over history and the world, and so of educating his people to trust in him. The prayer of the Psalms is the great school of this trust.
Jesus asks for childlike abandonment to the providence of our heavenly Father who takes care of his children’s smallest needs: “Therefore do not be anxious, saying, “What shall we eat?” or “What shall we drink?”. . . Your heavenly Father knows that you need them all. But seek first his kingdom and his righteousness, and all these things shall be yours as well.”
Providence and secondary causes
God is the sovereign master of his plan. But to carry it out he also makes use of his creatures’ co-operation. This use is not a sign of weakness, but rather a token of almighty God’s greatness and goodness. For God grants his creatures not only their existence, but also the dignity of acting on their own, of being causes and principles for each other, and thus of co-operating in the accomplishment of his plan.
the supreme moment in history, the beginning of humanity’s Redemption.
An inscription from the 16th century on the eastern façade of the Basilica hosting the Holy House reads: “Christian pilgrim, you have before your eyes the Holy House of Loreto, venerable throughout the world on account of the Divine mysteries accomplished in it and the glorious miracles herein wrought. It is here that most holy Mary, Mother of God was born, here that she was saluted by the Angel, here that the eternal Word of God was made Flesh….”
After Jesus’ Resurrection, the house was transformed into a church where St Peter and the Apostles placed an altar and where St Peter celebrated the First Eucharist after the Resurrection. That is where the Divine Sacrifice was celebrated for the first time.
As Enza Ferreri puts it:
So it was the place where the Incarnation occurred twice: first when Christ became man in Mary’s womb and then when, during the First Eucharist, His body and blood were transubstantiated and the Real Presence was in the Eucharist. Even today, in the Holy House, the Altar of the Apostles is preserved, miraculously transported with it; in the place where the Blessed Mother had made Jesus descend to earth for the first time, Saint Peter pronounced the words of the Consecration, which are still repeated at every Mass.
Chronology of the change of location

May 9, 1291, the Holy House is still in Nazareth

On the night of May 9 to 10, 1291, the House traveled to Trsat, Croatia.

On the night of December 9 to 10, 1294, the Holy House disappeared from Tersatto and landed and stayed for nine months in Ancona, Italy

In 1295, the Holy House moved to a forest that belonged to a woman called Loreta, near the town of Recanati. That is where the name Loreto comes from.

Between 1295 and 1296, the Holy House was miraculously transported to a farm of the Antici family on Mount Prodo.

Four months later, the Holy House departed and landed on a road connecting Recanati to Ancona, where it remains to this day.

The walls of the House, with no foundation, are supported partly over open air.

Why did the Holy House finally come to rest across a road?
