Who Is Buried Inside the Library of Celsus?
The Roman senator Tiberius Julius Celsus Polemaeanus is buried inside the Library of Celsus, in a decorated marble sarcophagus in a crypt under the apse. His son Julius Aquila built the library in his memory, so the building is a library and a tomb together.
The walls of the book niches were double, with a gap between the two layers. It probably helped to keep the humidity and the heat away from the scrolls.
Later an earthquake threw the front down, and it was laying in pieces for centuries. The facade you see today was rebuilt between 1970 and 1978 from the fallen blocks. I wrote about the excavations and restorations of the library in another article.

Which Gate Stands Next to the Library of Celsus?
The Gate of Mazaeus and Mithridates stands next to the Library of Celsus. It was built in 4 or 3 BC as main entrance of the Commercial Agora, so it is more than a century older than the library. The inscriptions on it name Augustus, his wife Livia, his daughter Julia and her husband Agrippa, together with two men called Mazaeus and Mithridates, who probably paid for the gate.
Who Lived in the Terrace Houses of Ephesus?
Rich families lived in the Terrace Houses, so people also call them the Houses of the Rich. They are luxury homes built on three terraces, on the slope opposite the Temple of Hadrian. The oldest one goes back to the 1st century BC, and some were lived in until the 7th century AD. The floors have mosaics and the walls have frescoes.
Most tours start at the Upper Gate and walk downhill, so you reach the Terrace Houses on the way to the Library of Celsus. Besides, a modern roof protects them from rain too. Please keep it in mind that the Terrace Houses are not wheelchair accessible.

Who Was Soranus of Ephesus?
