No idea what this is or what the letters might be.

It's Latin.

It says "Don't dead open inside."

Was your house built on the site of a previous house?

[–] Xyphius@lemmy.ca 7 points 11 months ago (2 children)

it actually was a street prior to 1954

Okay. You said it was like ten inches down, so I'd guess it's probably not something related to your house, it's probably some bit of infrastructure from the old street. Which means we should be thinking in the realm of "outside municipal access covers", and not "something installed to make my house better".

10” isn’t all that deep. 4-6” slab with some subgrade. That’s 10” and would be about the depth for backflow preventers. Which that likely isn’t. But depth means nothing.

Uhhh was it a bombed out one?

[–] redacted_name@lemmy.ca 12 points 11 months ago (1 children)

What are/were the names of the local water, electricity, gas companies?

Either that or a prototype slime monster trap...

[–] Xyphius@lemmy.ca 2 points 11 months ago (1 children)

it's changed over the years. I'll check what it was back in the 50's

[–] athos77@kbin.social 6 points 11 months ago (1 children)

Can you try that thing where you put a sheet of paper over the letters and gently rub a pencil sideways over it, see if you get any more details on the letters?

[–] thisbenzingring@lemmy.sdf.org 10 points 11 months ago

Probably something like a sewer drain access point

[–] MedicPigBabySaver@lemmy.world 8 points 11 months ago

Don't open that! If you do, I'll know where the next pandemic began.

Are there any wires attached that aren't in the picture? First thing I thought of was some kind of grounding device.

[–] Xyphius@lemmy.ca 3 points 11 months ago (1 children)

looks likes it's just surrounded by dirt

[–] 900footjesus@lemmy.world 4 points 11 months ago (1 children)

...and nothing underneath?

[–] Xyphius@lemmy.ca 1 points 11 months ago (1 children)

not that I've been able to see less I start digging

[–] 900footjesus@lemmy.world 0 points 11 months ago

I would do that. Start on the side away from the bolts and see if that is a lid.

[–] Grass@sh.itjust.works 5 points 11 months ago (1 children)

You don't have a call before you dig phone line in your area?

[–] Xyphius@lemmy.ca 2 points 11 months ago

I would have to yes.

[–] ICastFist@programming.dev 3 points 11 months ago (1 children)

Is that another cover lid with screws? The letters look like C U B E, though it could be a 6 and an 8 where I think it's C nd B

[–] LillyPip@lemmy.ca 2 points 11 months ago

Not sure it helps, but I fiddled with the levels & stuff to try to make the lettering clearer. Didn’t have much success, but I do see something that could be ‘co’ to the right:

Adjusted image

[–] amansman@sh.itjust.works -2 points 11 months ago (1 children)

No harm in spinning the bolts out I wouldn't think. If it's sewer maybe it's covering a conventional looking plug cap.

[–] Son_of_dad@lemmy.world 18 points 11 months ago (1 children)

If it's pressurized there could be harm

[–] greyhaven7@lemmy.world 2 points 11 months ago

Especially if it is suage
