What is this Pipe? Should I be worried?

Hello,
I recently opened a wall looking for a sink drain. What I found (in addition to the drain) was a giant pipe, about 10 inches wide with walls about 3/4 inch of concrete between metal. We went into the basement and could not find the bottom of it. Then I opened up a place that had a patch over it and found the end of it broken and jagged. I then went into the attic and found the other end, it looked like at one time it went through the roof or something, because there was a patch of wood above it, and it was jagged on that side too.

I have 3 pictures, 2 from the wall that I found the pipe in and one from the basement where it shows the jagged end in the basement ceiling.

My question is, it looks really heavy and unsupported, is it dangerous? What is it? Could previous owners of the house have messed up the structural integrity of the house?

Maybe a vent for a furnace or fireplace?

More than likely the pipe is the remnant of your previous main sanitary drain for the house. If it is cut off at both ends and capped no one should have a problem about removing it.

It is not capped on either end, that is insulation stuffed in it. It runs vertically and does not appear to have any other pipes or anything going into it, or a place for any other connections to it.

Did they make them out of concrete and 10 inches wide in the past?

Maybe asbestos. Asbestos looks like concrete and is heavy.. I have only pulled asbestos pipe out of the ground.. If it is I would just leave it...Its I guess concrete with asbestos mixed in.....

Transite - Wikipedia, the free encyclopedia

At 10" in diameter it could have been a flue for an old furnace. Are there any signs that a furnace once was located below the spot where it terminates in the basement? It also has the appearance of a glazing over the pipe. If you want to remove it perhaps you should have a piece tested for asbestos. In this form it would not be particularly prone to dusting and spreading a quantity of fibers. I just had some transite siding tested and it cost about $ 50.00.
