To those from the Western hemisphere, it’s always fascinating to hear that some homes and businesses from the times of the Greek philosophers still have inhabitants, and then you remember that the Western hemisphere is itself not without its own examples, for example some Mexican villages still have temples from the times of the Mayans.
Normal people houses don’t survive much longer that 500-600 years bc on fire and bombing, but town hall, temple, fort, palace and other administration building can be much much older.
Houses weren’t typically built with durable materials. Only fancy buildings could afford to be.
Still a few hundred years is much more than what most of today buildings can survived.
