Believe it or not, some of it was imported from Scandinavia! Ice in large quantities will stay frozen for a surprisingly long time. The larger the chunk, the smaller the surface-to-volume ratio.

Bury them in the ground and use them like a chest freezer, and keep the ground around them wet, this will almost certainly be cool enough for medicine, and I suspect for most other foods as well,.... after all, we are most likely to be eating anything fresh as and when we get it,..our stored food doesn't need refrigeration
They will be more of less rain proof, although you could always cover the door with plastic under the rock cover
I have only just remembered, SDs post reminded me but I also have a 12v fridge in the attic from my caravaning days,... thanks SD..
I have just been talking to the other half about this, and she suggested that because a fridge or freezer is insulated that the fridge wouldn't keep cool enough if placed in the ground as I have suggested.
So, with that in mind, maybe a single skinned metal box may work much better
....any thoughts?
I think it depends on whether you want to make things cool or keep things cool. On a warm day the ground will be cooler than the ambient air. So putting food in an uninsulated box in the ground will cool it down relative to ambient. On the other hand, if you have already cool food and want to keep it cool, then putting it in an insulated box in the ground will help. The ground will be less warm than the air, so the insulated box will need to work less hard to keep the heat out.
(Bear in mind it's always about keeping the heat out, never keeping the "cold in". Cold is simply the absence of heat)
I googled this, and it seems that the first guy to transport Ice was an American who cut ice from a Minnesota lake and it was transported to the West indies in 1806,.. ok not too helpful
It didn't take long for the Victorians to start doing this kind of thing,.... they would build an Ice house, a large [ usually subterranean ] house the bigger the better, close to a water source,.. they would then cut the ice in the winter and pack it into the Ice house as tight as they could, the ice was wrapped in a straw insulation, the more ice in the store the longer the ice kept, normally all year round,.. pieces of this ice were chipped off and sold
I have never seen an Ice house, but I know that similar houses were built on large Scottish Estates when they shoot hundreds of deer a week, they hung them in similar structures
None of this is much help to us as preppers though, I doubt many of us would be able to manage something like this, unless you lived in a large community
