62 year old home renovated about 3 years ago. This portion of the interior basement was
left alone. What is this - an old coal chute perhaps?

There is noting on the exterior of the home to indicate this is present.

As you can see it is seeping moisture. I suspect the interior box has corroded and
is now leeching moisture into the basement and then setting up mold.

So...

1) What is it?

2) Any concern about opening it up and looking inside?

3) How to remediate?

Is it under a chimney, or was it at one time? It looks like a
clean-out door.

TIA,
