The Greeks take their ancient ruins very seriously. Much of the city of Athens was built many years ago before any concern for antiquity was raised. Nowadays, if a builder wishes to tear down an existing site and construct a new building, archeologists must be called in if any ruins are discovered during the building process. A large set of ruins were discovered at this site so the city required that the builder alter their construction plans. The building was built over the ruins with viewing ports along the sidewalk and in front.
This new bank was built over the ruins in this cave.
