[1] Fum al Khalig is also known as Al-Hamra (el-ḥamra; literally: "the red one" in Egyptian Arabic).

Not only is it evidence of the past existence of Coptic Orthodox Christianity in Cairo outside of the Old City (being close to the northern tip of the district), but it is also one of few surviving pieces and large remnants of Coptic architecture that remains to this day.

These same masonry pillars, which still exist in the present, separate the nave from the aisles with six on each side.

[2] Today, only sections of the central sanctuary and the outer wall remain from the 8th-century building.

On the southern sanctuary, there is shrine that contains a number of beautiful icons embroidered in the Coptic style.
