There's probably a whole somewhere where a kinda developed culture could fit.
(I bet you meant "hole". Either way, it would help if you explained some what you meant.)
Undersea? Especially under the Pacific or under the Arctic?
Antarctica?
How about the bottom of Lake Baikal?
Maybe the upper regions of the tallest extensive mountain ranges? Are the Himalayas extensive enough?
Or of the most extensive tall mountain ranges? Are the Andes tall enough?
Does the Australian Outback count as a "hole"? What of Greenland's un-permanently-inhabited areas? What about the Sahara?
Just a few suggestions.
You said "without changing our history".
I think all of those places might work without changing history up until about 1500 CE; all or almost all up until about 1600 CE; and most up until about 1700 CE.
In the 18th century CE the world was being explored more and more by the West Europeans (who at that time are the ones whose history counts as "our history"), so places were dropping off the list of places where such a hole could be found after 1700 CE; nevertheless, I guess most or many of the places I suggested above would still be available to put your "hole" in without changing our history until about 1800 CE.
The bulk of the West Europeans' exploration was completed by the end of the 19th century CE, so only a few of those places would still be "holes" after around 1900 CE, if you wanted to keep history the same until then.
I think parts of East Africa's Great Rift Valley may have been available almost until 1900 CE, but become unavailable a few years to a few decades before then.
By 2000 CE (indeed, by around 1930 or 1940) other non-Western or non-European countries' histories had become relevant to "our history", and all of the above places had been "explored" by some industrial civilization or other to some degree (maybe just by flying over):
EXCEPT for under the oceans.
And I don't include the continental shelves as part of the "unexplored" areas.
By "unexplored areas" I mean benthic parts of the abyssal plain that are more than 150 meters below sea-level.
Or maybe, more than 400 meters below sea-level (like the bottom of the Dead Sea).
Or even more than 1 kilometer below sea-level (like the bottom of Lake Baikal).
