Blue Mosque
Six minarets and twenty million mosaic tiles inside Istanbul's most iconic skyline fixture.
The Sultan Ahmed Mosque — universally known as the Blue Mosque — was built between 1609 and 1616 under Sultan Ahmed I, and it remains one of the great architectural achievements of the Ottoman Empire. It sits in the Sultanahmet district facing the Hagia Sophia across a broad plaza, and together the two buildings define Istanbul's famous silhouette. The mosque earned its popular nickname from the roughly 20,000 hand-painted Iznik tiles lining its interior walls and ceiling in cascading shades of blue, turquoise, and white — a decorative scheme unlike anything else in the world. It also caused controversy at the time of its construction for having six minarets, a number previously reserved for the mosque in Mecca.
Visiting means crossing into a working, active place of worship — not a museum. You remove your shoes at the entrance, and non-Muslim visitors are directed through a separate side entrance. Inside, the central dome soars 43 metres overhead, supported by four massive fluted columns (the original design calls them elephant feet) and ringed by smaller semi-domes that cascade downward. The Iznik tiles are most striking at eye level and above, where the natural light from 260 windows filters through and shifts the colour of the interior throughout the day. Prayers happen five times daily, and the mosque closes to tourists for roughly 90 minutes around each prayer — something many visitors fail to account for.
The mosque is free to enter, which means crowds can be intense, particularly in summer. The courtyard itself — a colonnaded marble space with a central ablutions fountain — is worth taking time in even before you step inside. Go first thing in the morning or in the early evening for the most atmospheric light and the thinnest crowds. The neighbourhood around it, Sultanahmet, is heavily touristic but there are still good lokanta-style lunch spots a few streets back from the main plaza.
