The Blue Mosque, officially known as Sultan Ahmed Mosque, is one of Istanbul’s most iconic landmarks. Completed in 1616 during the rule of Sultan Ahmed I, it was built to rival the grandeur of nearby Hagia Sophia and remains a masterpiece of Ottoman architecture.

Its name comes from the stunning over 20,000 handmade İznik blue tiles that adorn its interior, casting a soft, serene glow under sunlight filtering through over 200 stained glass windows. The mosque’s design blends traditional Islamic elements with Byzantine influences, most notably in its massive central dome flanked by smaller domes and six elegant minarets — a rare feature that once sparked controversy.

A fun fact: It’s the only mosque in Istanbul with six minarets, which at the time matched the number at the Grand Mosque in Mecca. To avoid conflict, Sultan Ahmed ordered a seventh minaret to be added to Mecca’s mosque.

Today, the Blue Mosque is an active place of worship and welcomes millions of visitors each year. Entry is free, though modest dress is required, and it closes to tourists during prayer times. It's a must-see for anyone visiting Istanbul — not just for its history and architecture, but for the tranquil atmosphere it offers amid the city's bustle.
