The Coptic Orthodox Church of St. Barbara (Coptic: ϯⲉⲕⲕⲗⲏⲥⲓⲁ ⲛⲧⲉ ϯⲁⲅⲓⲁ ⲃⲁⲣⲃⲁⲣⲁ or Sitt Barbara) is one of the many famous Coptic Orthodox parishes that can be found in the district of Coptic Cairo. The building is located on the eastern part of the Babylon Fortress and is one of the oldest buildings in Cairo, dating back to the 5th or 6th century AD. However, like many other buildings of Coptic architecture, it was rebuilt several times, most notably by the end of the 11th century.
