The Bibliotheca Alexandrina Excavations collection is among the most important collections in the Antiquities Museum as it reflects the remarkable artistic style and reveals the nature of the daily life during the Hellenistic, Roman and Byzantine periods. It is also regarded as the core of the Museum collections, as it was discovered during the construction of the New Bibliotheca Alexandrina. The BA Antiquities section comprises 111 artifacts, the most important of which are the marvelous mosaics which are believed to have paved the floors of the royal palaces that once stood in this region.
