Like the Parthenon in Greece, the Library of Celsus is all but a structure in ruins, yet it’s still considered a marvel. Located in Ephesus, Turkey, the Library of Celsus was built in homage to the great Roman Senator for which the edifice is named. It once stored 12,000 scrolls for public perusal. Celsus’ remains lie beneath the main entrance of the library and it was a highly unusual practice for any person to be buried within a library.
