This is the landmark of the Library of Celsus, which is also the attraction of a large number of travel enthusiasts who like us to appreciate and explore a history that is not hidden: this year only allowed men to enter. The library, originally hidden inside a tunnel leading to the brothel, provides an excuse for men to return to the land they are really interested in. The wife also thought that her man could study tirelessly in the library for a whole day. The size of the library was then the second largest in Asia Minor. It had a collection of 12,000 books, second only to the city of Bergama. The building faces the east, so the reading room can make the most of the morning light. The library has survived fires and earthquakes, and its front door is still standing. The most recent renovation was in 1970. The four goddesses are clearly visible in the porch of the gate, behind the stone pillars, representing wisdom, destiny, learning, and virtue. Currently seen as a replica, the authenticity is hidden in the Vienna Museum in Austria.
