Also known as the ‘Blue Mosque’ for the blue tiles that adorn the interior walls, the Sultanahmet Mosque is a working mosque in the center of Istanbul and one of the city’s most famous landmarks. Built by Sultan Ahmed I during the early 17th Century to reassert Ottoman rule following the war with Persia, it was designed with one main dome, eight secondary domes and six minarets. It combines Byzantine Christian elements with traditional Islamic architecture, and the interior is lined with 20,000 handmade Iznik-style ceramic tiles.
It is possible for non-Muslims to visit the mosque outside of prayer times and take part in a free presentation about the mosque and Islam. Women need to cover the heads and shoulders, and both men and women need to cover their legs.
