Using natural caves as cool stores

I sooo... wish my property had a cave large enough to secure as a "cold cellar". There are so many things I would put in such a place.

The right sort of cave with appropriate access enclosed keeps the temperature very steady in my ecosystem. I've debated at times choosing a spot and using my rock drill to create such a thing, but it would be a huge job and I've got less time-consuming projects to work on!

I have read that in the early days' people cut large chunks of ice that were kept in caves to be used year-round.

I have toured a lot of caves across the US, like Carlsbad Caverns and Mammoth Cave as we like exploring caves.

Due to living in limestone country, there are a lot of caves in the area where I live though I have not been to them.

As hot as it has been lately it would be fun to visit some caves.

A few years ago I visited the beer museum in Bamberg, which is built down into a large hill.  One of the rooms was indeed where they kept ice.  (I tried to find online pictures but there's not much to see, just a big room with stone walls.)

This is also how Biergartens came about, from Wikipedia:  

Numerous conflagrations had occurred, which resulted in the prohibition of brewing during the summer months. In response, large breweries dug cellars in the banks of the River Isar to keep their beer cool during storage. "Beer cellars" for consuming beer on premises naturally followed.

To further reduce the cellar temperature during the warm seasons, 19th-century brewers layered gravel upon the cellars by the bluffs and planted horse-chestnut trees for their dense spreading canopies and shallow roots, which would not damage the cellars.[4] Soon afterward, serving cool beer in a pleasant shaded setting emerged. Simple tables and benches were set up among the trees, creating the popular "beer garden" that is known today.

I always envy you outer hemisphere people your root cellars.  Average cave temperature around here is almost 80 degrees Fahrenheit. That's 26 Celsius for all those on metric and they're very humid spaces. Anything we'd store there we might as well keep in the house.
