El Korba Square is an open museum without walls. This square was built by a foreigner and it becomes Egypt's most famous square. It is filled with many architectural masterpieces of ancient style.

El Korba Square is characterized by its triangular shape as it starts from Al-Ahram Street starting from the Heliopolis Hotel (now the Presidential Palace) until the Basilica Church and Nazih Khalifa Street (formerly Baron) that intersects with Al-Thawra Street until Baron Empain Palace, and from inside Al-Korba Baghdad Street that also meets Al-Thawra Street.The naming of the square with this name “El Korba” is due to the street being turned around, unlike the usual streets at that time, and the word in Italian means a bend or an arc. As the metro used to take a bend or turn around in this place on its return journey coming from Fouad Al Awal Street (Downtown), so the Belgian conductor  used to call out the word (Korp), which became thename for this place.

This three-sided square was distinguished by huge buildings designed with a unique architecture at the hands of Baron Empain, and from this square was the beginning of  Heliopolis, with its historical bouquets, which is famous for the square of Korba and far from the timeless architectural masterpiece the “Palace of the Baron Empain” . As well as the palace of "Baghos Nubar Pasha", there are three historical evidences that bear witness to the nobility of Korba, and are: the Basilica Church and the Church of the Korba, the Heliopolis Palace Hotel (now the Presidential Palace), and the jewel in the crown of Korba which the work began on it in 1906 and was opened in 1910 in a grand ceremony.

This is the first building in El Korba in which the Belgian “Ernst Jassbar” participated, as he set the general design for it while the French Alexander Marcel placing its interior decorations taken from the works of Arab inscriptions.

The palace was two hundred meters and topped by a dome height of 55 meters ٬ and it has luxurious halls for receptions, and 400 rooms that are luxuriously furnished, and its main hall is circular specially woven for its Iranian carpets and its diameter was 30 meters.

The second masterpiece is the Church of the Baron or the Basilica of the Basilica, which was built by one of the most important builders of Heliopolis, the French Alexander Marcel, in 1910, at the request of Baron Empain, and was from his own money and away from the Heliopolis Oasis Company at that time. The church drawings were placed in the Byzantine style, which is a miniature image of the Hagia Sophia Cathedral in Istanbul. The Basilica Church is located at the beginning of the Al-Ahram Street. After the death of Baron Empain, the church became part of the inheritance of his second son, Louis, and the Louis family later donated it to the Catholic Church in Egypt.
