Holy Mary, Virgin Mother of God,
who was conceived without sin,
I choose thee, this day,
for the lady and Mistress of this House;
I beseech thee through thy Immaculate Conception,
to preserve it from pestilence, fire and water;
from lightning and tempests,
from robbers, from schisms and heresies,
from earthquakes and from sudden death.
Bless and protect, O holy Virgin,
all its inmates,
obtain for them grace to avoid sin,
and save them from every other misfortune and accident.

Amen.
