What is this please?

Discovered this area of wall that had a metal covering
Took the cover off and discovered it was full of debris & some kind of outlet was blocked
It feels like the whole column downwards is full of debris
The debris is very sooty also
Help

Looks like a soot door. Basically an access door into a chimney

Thanks for that. I have seen them before and wondered what they are.

Now I know.

Looks like chimney has been removed and a porch has been added.
