The library was built in 135 CE by Julius Aguila in honor of his father, Celsus. It was representative of traditional Roman architecture and contained between 12,000 and 15,000 rolls, which were protected by the double walls. Celsus is buried within a vault in the library. It was destroyed in 265 CE when the Goths invaded.

The Temple is considered one of the seven wonders of the world. Dating back to 550 BC, it was supported by 127 columns, and was 4 times larger than the Parthenon. It was designed by the architect Creton Chersiphron, and its rumored that construction took almost 120 years. It was burnt down the same night that Alexander the Great was born. It was rebuilt by Dinocrates with practically the same dimensions as the original. The temple was mentioned in the book of Acts, where Paul preached against the statues made for worshipping Artemis (Diana).

The theater was started under the reign of Claudies from 41-54 CE, and finished under Trajan from 98-117 CE. It seated approximately 25,000 people, and was an impressive sight at 495 feet in diameter. Even today concerts are held there, where the likes of Diana Ross and Sting perform.

St. John brought the Virgin Mary to live in Ephesus, while he wrote his gospel. The Pope has visited it on a few accounts, and today it is visited by many as a pilgrimmage spot.
