Seeking some mumsnet wisdom...Moved into a 1920s house a few months ago. Lots of original features but the house has been extended to the side to add a garage/kitchen extension.
This is on the wall at the foot of the stairs by the front door. I presumed it had been added to fill the space previously used as a window but I'm not so sure. A friend mentioned something about catholic families using them for holy water and to bless themselves when they leave/enter the house. Anyone seen one before?
