Next to the entrance to the Temple of Athena, this 14th-century mosque is a simple structure – a dome on squinches set on top of a square room – built before the Turks had conquered Constantinople and assimilated the lessons of Aya Sophia. It was constructed with materials from an 6th century AD church and is one of just two remaining Ottoman mosques of its kind in Turkey (the other is in Bursa). Hüdavendigar is in fact a poetic name for that city.
