This was originally what cellars and basements were for. Ground temperature was stable relative to outside temperatures, so it was warmer than freezing during winter but colder than outside during summer. Thus it could help preserve food.

Some old farm houses still have that around here. But it is outside below a small hill or a slope. Some call it Kartoffel Keller. And some still use it for long time storage.
