ᐅ Could this arch be self-supporting?

Good evening everyone,
I would like to enlarge this arch from a curved archway to a rectangular opening. However, I’m not sure if a support beam has been installed there. My biggest concern is that the arch might be load-bearing. But is that even possible?
According to the original building plan from 1960, there was no arch but a wall with a cavity. I’m attaching a photo as well. Today, however, the arch is there. I hope someone can give me some advice.

I would say the wall is about 17cm (7 inches) thick. The opening is approximately 2 meters (6.5 feet) wide. How do you conclude that there is no lintel installed?

Back then, the arch was built using wood, and the remaining parts were filled in with masonry. This way, the arch becomes self-supporting.

I can understand that. But does this look like typical arches from the 1950s/60s to you? That’s when the house was built! And since it’s a load-bearing wall, is this simply possible?

In your case, would the arch or the bricks be purely decorative or load-bearing? They definitely need to be removed 🙁

As mentioned before, the arch can support loads even when this flat. In my opinion, you shouldn’t just remove it. I would definitely consult a structural engineer. Once they have the reinforcement plan, they can determine whether the slab is designed to rest on supports in one direction only or in both directions.

If in doubt, you’ll have to install a beam underneath. It’s not exactly rocket science.

Have you drilled a hole yet?

Unfortunately, I won’t have access to the house until September 1st. However, I naturally wanted to gather information about such matters well in advance.
