For almost two millennia, specifically in the middle of the second century AD, the Roman Emperor Trajan ordered the construction of a fortified castle to secure Roman military protection. This castle served as the first line of defense against any potential uprisings from the south or north, and was strategically located in the middle of Egypt, connecting the northern coast to the southern desert. The Roman Emperor Arcadius later reinforced and expanded it in the fourth century AD, according to the Coptic scholar Marqus Samiqa Basha.
The Babylon Fortress has a significant historical importance that extends to the Islamic conquest of Egypt. In 641 AD, “Amr ibn al-As” led an army to Egypt, and after a seven-month siege, the fortress fell into the hands of Amr ibn al-As, marking the beginning of the Islamic rule in Egypt.
Some narratives suggest that the name of the fortress was inspired by the Babylonian capital. According to a story, when the pharaoh Senusret defeated the Babylonians, he brought prisoners to Egypt to enslave them, but they rebelled and built a fortress to defend themselves. Since then, it has been named Babylon.
Another name for the fortress is “Al-Shamaa Palace,” which is derived from an ancient tradition. At the beginning of each month, the towers of the fortress were decorated with candles, allowing people to follow the movement of the sun from one tower to another when they were lit.
The Babylon Fortress has a strategic and unique location in the Old Cairo district of Fustat, next to the Coptic Museum. It was chosen for its control of the eastern desert road and its military significance. It is also close to the Nile and controls the road leading to the northern and southern coasts, serving as a shield against any protest or revolt.
The area of the fortress is about 500 square meters, and stones from Pharaonic temples were used in its construction, which were then completed by red bricks. Currently, only the north gate of the fortress and two large towers remain. One of the towers has a suspended church built on top of it, while the other has the Roman St. George Church. Several other churches and religious sites are located inside the fortress, including the Abu Serga Church, the Virgin Qasr al-RihanChurch, and the St. George Monastery for nuns.
