What is "bilbeis"

Bilbeis ( ; ) is an ancient fortress city on the eastern edge of the southern Nile delta in Egypt, the site of the Ancient city and former bishopric of Phelbes and a Latin Catholic titular see.

The city is small in size but densely populated, with over 300,000 residents. It also houses the Egyptian Air Force Academy complex, which contains the town's largest public school in Al-Zafer. The mosque of Sadat Qureish, which is the oldest mosque in Egypt, and one may say the entire continent of Africa, is located in Belbeis.
