The Library of Celsus, the façade of which has been carefully reconstructed from all original pieces, it was originally built c. 125 AD in memory of Tiberius Julius Celsus Polemaeanus, Ancient Greek  who served as governor of Roman Asia (105–107) in the Roman Empire  Celsus paid for the construction of the library with his own personal wealth, and is buried in a sarcophagus beneath it.[ The library was mostly built by his son Gaius Julius Aquila[ and once held nearly 12,000 scrolls. Designed with an exaggerated entrance — so as to enhance its perceived size, speculate many historians — the building faces east so that the reading rooms could make best use of the morning light.
