What area on the earth has seen the sun once and will never see it again?

The area on Earth that has seen the sun once and will never see it again is the location of the North and South Poles. Due to the tilt of the Earth's axis, regions within the Arctic and Antarctic Circles experience polar day (midnight sun) and polar night. When the sun sets at these poles during the winter months, it will not rise again for several months, making it a unique phenomenon of perpetual darkness. Once the sun sets at the poles during this time, that specific moment will never occur again.
