Abu Haggag Mosque

The Mosque of Abu Haggag (Arabic: مسجد أبو الحجاج بالأقصر) is a mosque in Luxor, Egypt. It is integrated into the structure of Luxor Temple, an Ancient Egyptian centre of worship, making it one of the oldest continuously used temples in the world, dating back to the reign of Pharaoh Amenhotep III in the 14th century BC.The mosque stands on the ancient columns themselves. That part of the Luxor Temple was converted to a church by the Copts in 395 AD, and then to a mosque in 640, more than 3400 years of continuous religious worship. Hence, the Luxor Temple is the oldest building in the world at least partially active for other than archeological or tourist purposes.
