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.
