How to tell if it is load-bearing?

[banana]

Hello, soon I'm going to expand the kitchen by tearing down an interior wall.
I live in an old wooden house from -29.
In the wall that will be torn down, there is the chimney, so it will remain in the middle of the kitchen like an island, with a stove and wood stove standing against it.

But how do you know if it is a load-bearing construction, does the ridge system always apply?
In the attic, you can see that the beams (especially one) are more or less embedded in the chimney with cement, but I naturally do not plan to make any interventions on these beams, but how can I know if the wall is load-bearing?
I have a crawl space, so if the foundation stones are under the wall, could that indicate that it is supporting, or how do I know?

Yep, then it is most likely load-bearing. But I recommend you contact a structural engineer before making any modifications.

What is the model of the trusses? Does the wall run parallel to or cross the bottom chords of the trusses? Where is the wall located in the house, directly under the ridge or closer to the outer wall?

The wall runs parallel with the rafters, originally situated between two exterior walls, but later the house was extended. I assume the original was about 5x30 meters, with 2 walls on the 5-meter side... Hmm. So, an elongated house. Originally, it was a two-family house with a dividing wall in the middle and an entrance on each short side, but the dividing wall has been removed at some point, and that should probably have been the load-bearing one. A bit tricky to explain, hope it's readable. I'll see if I can upload a picture today.

Not a bad house!

Then you can have a bowling alley indoors.
