Hi, seeking any opinions/idea on the historical roots of this mysterious "hole". :-)
I've been removing wallpaper from the walls of the room that's next to the kitchen. In removing one section, I saw an area that appears to be a cement "patch" for a hole in the wall.
House built in 1887/1888, Queen Anne in Massachusetts
The baseboard under the patch area is slightly different than the baseboard in the rest of the room. They did a good job of matching it, but I can see slight differences up close. The patch area is 29" high measured from the floor, and 18" wide for most of it, with that slight bump on the left edge near the top.
There's a very faint line that looks like a rectangular 'box' impression on the plaster wall that runs around the patched area. Maybe some decorative metal frame resting against the plaster wall, with a cavity behind grating?
I find the irregular shape of the left edge odd. I can see the horsehair plaster wall 'cut' kind of slanted:
More clues in the Basement:
The basement 'ceiling' is all open, and I can easily see the area that's directly under the patched wall area. Because the electric receptacle in the baseboard there is on a knob-and-tube circuit, I can identify the spot exactly and see the portion that's directly below the space behind the wall patch:
There is a large patched "hole" in the basement 'ceiling' at the spot:
