Electric cars will replace gas-run cars at the Salaheddin Citadel archaeological site in an attempt to reduce the rate of pollution from the excess number of cars that circulate in  the area.

Cars will no longer be allowed to enter the site and around the different monuments in the area.

Salaheddin stands as one of the world’s greatest medieval ruins and houses a number of mosques and several museums, including the Mohamed Ali Mosque; Al-Gawhara Palace museum; the Carriage Museum and the National Military and Police Museums.

The citadel was built on a spur of the Muqattam Hills. It was once Cairo's seat of power for succeeding caliphs, sultans, ministers and pashas until the time of Mohammed Ali in the 19th century. The citadel stopped being the seat of government when one of Egypt’s rulers, Khedive Ismail, moved to his newly-built Abdeen Palace in the 1860s.

The citadel is maily divided into three sections: the main fortress and eastern walls, which were built by Salaheddin Al-Ayyubi in 1176; the southern enclosure, which has 19th century walls; and the lower enclosure extending down the western face of the hill, with its main gate opposite the Sultan Hassan Mosque.

Mohsen Sayed Ali Secretary general of the Supreme Council of Antiquities (SCA) at the Ministry of State for Antiquities (MSA) said that a visitor's path would laid out in order to facilitate tours.
