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 town I live in burned down almost completely in 1787, so most historic buildings in the city were built after that. The city wall is probably the oldest structure, but it’s unknown when it was originally built. The oldest building with a known year of construction is most likely the church that was built in 1246.
