Located at Selcuk, Izmir, the library which was build between AD 115 and 117 during the Roman times is two-storied. It is estimated that it housed 12.500 books once upon a time.

Moreover, as the building was encircled by a second wall on the exterior, the library is very well protected against humidity both at the bottom and on the sides. It is observed that there are two rows of rectangular niches one above the other in the back and side walls. The existence of a third niche in the building indicates that the building was in fact three-storied although it seems to have two stories from the outside. Manuscripts were kept in the form of scrolls on the upper floors consisting of galleries. The reading room was burnt during the earthquakes affecting the region in the 3rd century AD, but repaired at a later date. It is guessed that the façade also collapsed as a consequence of an earthquake in the medieval times.
The library has a façade with so rich architectural decoration. The architectural components on the façade are supported by four pairs of columns. Behind each pair of columns is a niche in the wall and gates and windows between each pair. As understood from the inscriptions on the banisters, Gaius Julius Aquilla, who became a consul in AD 110, had the library built as a heroon for his father Gaius Celsus Polemeanus and left 25.000 denarii for the upkeeping of and purchasing books for the library. Aquila’s heirs had the library completed (circa AD 135). The sarcophagus of Celsus carved out of marble is still standing in the vaulted chamber under the large central niche. The bones of the deceased were found in a lead coffin in the sarcophagus.
The forecourt of the building was converted into a pool in AD 400. Large reliefs from a monument erected in the pool in order to commemorate the victory of Marcus Aurelius and Lucius Verus over the Parthians were unearthed during excavations and are now ion display in the Vienna Archaeological Museum.

Theatre of Asclepium

 
Its past going back to the 4th century BC, Medical City Asclepium was established in dedication to Asclepius, god of medicine in mythology and maintained its activities as a renowned medical centre until the 5th century AD. The propylon of Asclepium which proves that Bergama was an outstanding medical city in the antiquity is called Viran Kapi (Ruined Gate) and still standing today.
It is known that there was an inscription reading “Death is not admitted” and of those who were examined at the entrance, the fatally sick patients who might not possibly recover were not admitted in. Those patients who were admitted in used to walk in the 650m long sacred street, drink and wash themselves in the curative water which is still drinkable at present and then start to be treated. In the Asclepium where it is understood by the findings that operations were even performed, treatment was applied by the use of medicine, herbs, music, mud and sun baths. Known to have brought up such famous physicians as Galen, Asclepium also houses the serpent column which is the symbol of medicine. Moreover, in Asclepium, there is a theatre seating 3.500 spectators which is still in use at present.

 
Ahmed Adnan Saygun Centre consists of three major parts: Town Square, Culture Platform and Centre of Arts. At the Centre are located a hall seating 243 spectators and exhibition spaces spreading across three stories and interconnected by a bridge as well as the great hall. Architect Tevfik Tozkoparan, who is the project owner, converted the trolleybus terminal and maintenance workshop of the past which is but a memory now into a centre for artistic activities.
AASSM comes to the forefront with large galleries which shall host plastic arts and contemporary arts as well as the concert hall which has been brought into being with a careful acoustic plan. The concert hall which is the jewel of AASSM has proven a grandiose concert hall from the projecting stage to the application stage. The acoustic project having been undertaken by the British company ARUP which is experienced in its own field, the hall was built without overlooking any fine details such as the structure analysed according to the instruments to be played thereon of the platform on which the orchestra shall play.
The pre-stage platform with an elevator in the concert hall seating 1153 spectators reaches a height equal to the stage at its top-most level, thus allowing performances attended by a large number of instrumentalists, and in case it is lowered down to the level of the spectators, it may allow for an additional seating capacity. The platform which functions as an orchestra pit when it is lowered to its lowest level allows for the realisation of such performances as ballet, modern dancing or opera as well.

Çeşme Castle

 
The most-visited historical work in Cesme, the castle built by Beyazid II is now used as a museum. And the Cesme castle was built by the architect Mehmet, son of Ahmet through the governor of Aydin Mir Haydar upon the orders of the Ottoman Sultan Beyazid II in 1508. The initial construction of the castle took place just by the seaside. However, it took its present position due to the filling in of the sea in subsequent years.
The castle and the harbour protected the trade and war ships against adverse weather conditions and enemy attacks. The southern gate of the fortress bears all the characteristics of the Ottoman architecture. The Cesme Archaeological Museum is located within the castle which has reached the present ay in a very good state of preservation.
The Museum of Cesme was first opened to visitors as a weapons museum with the weapons brought in from the Istanbul Topkapi Museum in 1965 and maintained its status until 1984. As the weapons displayed started to oxidise and deteriorate due to excessive humidity in the hall, they were transferred to the museums in Izmir and Odemis. The same display hall has been re-arranged and is now used to display the works unearthed in the course of the excavations carried out at the ancient town of Erythrai (Ildiri).
