Where do you put the wire pinned along the edge of the roof so that ice sheets don't fall on people's heads? Or maybe that's like a horizontal lighting rod. I'm an artist and I'm trying to make my hobby rendering of an orangery as realistic a possible and don't want to be told by some roofer 'you did that wrong'.
The only similar building I found on the internet was 'Bábszínház-Narancsház' but it isn't exactly the same. The building is in East Brandenburg and it's just a ruin without a roof.
