The Holy Family moved from the Filuseyat area until it reached “Kassion’s Head” or Ras Al-Kassion that overlooks Lake Bardawil, located 38 km west of Al-Filuseyat, and to the east of Muhammadiyah on the sea road.
It was known in the Greco-Roman and Byzantine era as “Casius” and was known in the era of the Arabs as “Fortress of the Christians” or “Monastery of the Christians” or “Ras al-Qallus”
Historians of the Roman era pointed out that there was a fort there, and it appears from the Arabic names that gave it that the fort and the monasteries and churches that followed it remained until the Arab era.
The area is famous with its fresh water well above sea level, and the presence of palm trees.
Archaeological work has proven that it has antiquities belonging to several eras, including the Byzantine era. There are also churches, monasteries, and the remains of an archaeological cemetery and the remains of houses, as well as Pottery cracks and red brick molds dating back to the Greco-Roman period were also found.
Yaqut al-Hamawi mentioned it in the book “Mu’jam al-Buldan” as Ras al-Qallus, and that it is a protrusion that goes out into the sea and has a fortress in which people live, and they have gardens and fresh water.
It came in the book Description of Egypt (Part III) as having a water tank at the foot of the sand dunes and huge amounts of clay pottery on the seashore.
The Holy Family left this place and headed walking to “Muhammadiyah”.
