Heliopolis is a suburb of Cairo located to the north east, though there is no break between the cities as there was when it was first constructed in 1906. At that time the building style of the city, known as Masr al-Gedida or New Cairo had a mix of architecture set in a garden environment which reflected the tastes of the original promoter, Baron Empain, who built the Tram system in Cairo. Originally there was a strictly enforced building code with considerable neo-Arabic style used in buildings, but there are also some exotic dwellings in the area.
