Qusia has an excellent climate, with cold and dry winters and hot summers. The city of Qusia in Pharaonic times was the defender of the northern border of the Southern Kingdom. There are, as a result, many archaeological shrines such as the Mer monuments, Al-Qusiyir Monastery which overlooks the Nile, the Burnt Monastery, and some commercial premises.

Jesus, peace be upon him, son of the Virgin Mary, visited Qusia and stayed six months and ten days in the area of the Burnt Monastery. Qusia is the oldest Egyptian city and was the capital of Region 14 in Middle Egypt. During their occupation of Egypt, the Hyksos were confronted by the princes of Qusia who stopped their advance and thus protected the Egyptian kingdom from collapse. These princes allied themselves with the princes of Tiba to fight the Hyksos and had a large role in defeating them. The first battle against the Hyksos was fought in Qusia, and there is a board commemorating their victory over the Hyksos at Al-Barbh area in Zorabi Qusia. Nothing was left of the old city except Zorabi area, which was built over the monuments of old Qusia.
