Stone pillar in conservatory damp

this is heated along with the living space.

That simply won't be enough. In the worst case, this thermal bridge is even diagonally away from the heating of the living space. The only solution is to heat closer.

Eliminate the cold bridge. But that's certainly not what you want to hear.

Unfortunately, insulating is very difficult, and it wouldn't look nice visually either. Thank you for the answers, I will try to heat the stone column pointwise. Just don't know yet what works best here. Many thanks

Have you ever tried putting a small fan to circulate the air? It's definitely cheaper than heating.

Should that be a heater fan? Do you think I can insulate from the inside as well? Outside wouldn't look nice.

From the inside, it would make the problem worse and then it would nicely mold
