The temperature control is via the concrete foundation/walls, the

Here in the U.S., such cellars often have some kind of venting to cool them
down in the fall, otherwise that thermal mass actually keeps things warmer
than you'd like in early winter.
I have a root cellar with concrete walls under the front porch, with an
insulated door to the main cellar. Right now, there are some Brussels
Sprouts and Kale plants there to hopefully overwinter for seed next spring.
Never thought of posting a tour though.

I had recently looked into 'root cellars' and the optimun temp is
32-40 degrees and 90% humidity.

Keeps the fruit cold and keeps it from drying out. Sort of a wet
refridgerator.
