Abdeen Palace is a historic Cairo palace, and one of the official residences and the principal workplace of the President of Egypt, located above Qasr el-Nil Street in eastern Downtown Cairo, Egypt. Built on the debris of a house owned by Prince Bey, Abdeen Palace is considered one of the most sumptuous palaces in the World in terms of its adornments, paintings, and large number of clocks scattered in the parlors and wings, most of which are decorated with pure gold. Built by Khedive Ismail, to become the official government headquarters instead of the Citadel of Cairo (which had been the centre of Egyptian government since the Middle Ages), this palace was used as well for official events and ceremonies.The palace is today a museum, located in the Old Cairo district of Abdeen. The upper floors (the former living quarters of the royal family) are reserved for visiting foreign dignitaries. The lower floors contain the Silver Museum, the Arms Museum, the Royal Family Museum, and the Presidential Gifts Museum. A new museum, the Historical Documents Museum, was opened in January 2005.
