Cryogenically Frozen City

A city decides to cryogenically freeze itself to escape a looming disaster and emerges thousands of years in the future.

Take this opportunity to unravel the complexities of a society waking up thousands of years in their future. What remnants of the old world can still be found? How do they adjust to the new world and what kind of society do they find? This opens possibilities for themes like culture shock, adaptation, and time displacement.
