The Blue Mosque is one of the most prominent landmarks of Istanbul, especially when viewed from the First Hill or from the Asian shore of the Sea of Marmara. It is very impressive with its beautiful domes and semidomes, nice courtyards and six slender minarets.
The Blue Mosque was founded by Sultan Ahmet I. He ordered Architect Mehmed Aga to begin constuction in 1609 and the whole complex was completed in 1616.
