The Library of Celsus is one of the most well restored ruins in Turkey. What makes it unique is that while most libraries serve only the function of archiving books and documents, this one served as the final resting place of Tiberius Julius Celsus Polemaeanus, in whose honor the library was built.
Julius Celsus was a very wealthy and influential citizen who was elected consul of Turkey in 92 AD and governor of Asia in 115 AD. Seeing the Library of Celsus will give you an idea of how important wisdom was to the Romans, prompting them to store information in public buildings all over their empire. So important was knowledge to them that the architecture and foundation of the library were well planned out.
