أين تقع مكتبة سيلسوس الأثرية التاريخية؟
The Library of Celsus is an ancient Roman building in Ephesus, Anatolia, now part of Selçuk, Turkey. It was built in honour of the Roman Senator Tiberius Julius Celsus Polemaeanus, completed between circa 114–117 A.D. by Celsus' son, Gaius Julius Aquila (consul, 110 AD). The library was "one of the most impressive buildings in the Roman Empire" and built to store 12,000 scrolls and to serve as a mausoleum for Celsus, who is buried in a crypt beneath the library in a decorated marble sarcophagus. The Library of Celsus was the "third-largest library in the ancient world" behind both Alexandria and Pergamum.
