The Kariye Camii in Istanbul, Turkey; also known as the Church of the Holy Saviour in Chora is the most remote sight I visited in the city. It was a recommendation of my hosts and it really was worth the detour to the northwest end of Fatih. It was once a Byzantine Christian church that was converted into a mosque and is now serving as a museum.
Home of Atatürk
The Dolmabahçe Sarayı in Istanbul, Turkey – translated as the palace of the filled garden – is to me the most beautiful palace of the city. It is located on the European side in Beşiktaş, directly at the Bosphorus. It has been built from 1843 on and is one of the younger palaces, created because Topkapı Sarayı couldn’t adhere to European standards requested by the Sultan.
