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.
In the city I live in, the oldest building is from ~1280. It was rebuilt quite a bit in 1767 though. It has housed restaurants since the 1930s. I pass it every day almost on my lunch walk :)
