The Sultanahmet (Blue) Mosque

I captured this striking image of the Sultanahmet (Blue) Mosque in Istanbul on April 16, 2011, using a Canon EOS 7D. The mosque, constructed between 1609 and 1617 under Sultan Ahmed I, stands as a masterpiece of Ottoman architecture designed by Sedefkar Mehmet Ağa. Its name comes from over 20,000 handmade Iznik tiles that adorn the interior, predominantly blue, which gives the mosque its popular name.

The Blue Mosque features six minarets, which initially caused controversy as it matched the number at the Grand Mosque in Mecca. This was resolved by adding a seventh minaret in Mecca. The mosque’s central dome rises to 43 meters, surrounded by smaller domes, and the interior is illuminated by over 200 stained glass windows. The mosque's külliye includes Sultan Ahmed I's tomb and a madrasa.

Today, the Blue Mosque remains a functioning place of worship and a major tourist attraction, recognized as part of the UNESCO World Heritage site "Historic Areas of Istanbul" since 1985. Visitors are welcome year-round, but modest dress is required. Guided tours are recommended to appreciate the mosque's historical and architectural significance fully.
