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.
The oldest intact building in my city is from 1320 - so 700 years old. Baguely Hall, which is an old landowners hall.
The city itself - Manchester - dates back to the roman era and we have the remnants of an old castrum/fort in the city centre dating back to 79 AD - so 1945 years old. Surprisingly there were more complete ruins at the site but much of it was levelled during the industrial revolution.
