Blue Mosque: Istanbul's Crown Jewel of Ottoman Architecture

The Blue Mosque—formally known as the Sultan Ahmed Mosque—is one of Istanbul’s most iconic and awe-inspiring landmarks. Located in the heart of Sultanahmet Square, right across from the Hagia Sophia, this 17th-century masterpiece captures the grandeur of the Ottoman Empire and continues to function as an active place of worship today.

With its elegant domes, towering minarets, and stunning blue İznik tiles that adorn the interior walls, the Blue Mosque is a visual and spiritual anchor in Istanbul’s historic peninsula.

THE VISION OF A YOUNG SULTAN

Commissioned by Sultan Ahmed I in the early 1600s, the mosque was intended to reassert Ottoman power following military setbacks and to rival the beauty of the Hagia Sophia. Construction began in 1609 under the direction of architect Sedefkâr Mehmed Agha, a student of the legendary Mimar Sinan.

Sultan Ahmed was just 19 years old when he ordered the construction—and uniquely, he helped fund it not from war spoils, but from the state treasury. He passed away just one year after its completion, at the age of 27, and is buried in a tomb adjacent to the mosque.

WHY IS IT CALLED THE BLUE MOSQUE?

Though its official name is the Sultan Ahmed Mosque, it earned the nickname "Blue Mosque" because of the more than 20,000 handmade blue İznik tiles that decorate its interior. These ceramic tiles depict floral, geometric, and abstract patterns that reflect both Islamic artistry and Ottoman aesthetics.

When sunlight streams in through the more than 250 windows, the interior glows with an ethereal blue hue—an unforgettable sight for any visitor.

ARCHITECTURAL SPLENDOR

The Blue Mosque is a harmonious blend of Byzantine Christian and traditional Islamic architecture. Key features include:

• Six minarets – a rarity that sparked controversy at the time, as even Mecca’s Great Mosque had only six.
• A central dome measuring 23.5 meters in diameter and 43 meters in height, supported by four massive pillars known as "elephant feet."
• Cascade of domes and semi-domes creating a layered, flowing visual rhythm.
• Exquisite calligraphy and stained-glass windows enhancing the sacred atmosphere.

The mosque complex originally included a madrasah (Islamic school), hospital, soup kitchen, market, and mausoleum—elements that reflect the multifunctional role mosques played in Ottoman society.

EXPERIENCING THE BLUE MOSQUE TODAY

Visitors are welcome to enter the Blue Mosque outside of prayer times, free of charge. Modest clothing is required, and scarves are provided at the entrance for women. The mosque is still in active use, and witnessing a call to prayer here—echoing across the historic district—is a moving and unforgettable experience.

Major renovations have recently been completed, restoring many of the intricate details that had faded over centuries. With fewer scaffolds and clearer views, now is an ideal time to visit.

FUN FACTS ABOUT THE BLUE MOSQUE

• The Blue Mosque is the only mosque in Istanbul with six minarets, which initially led to criticism until the Sultan funded the addition of a seventh minaret to the Kaaba in Mecca to resolve the issue.
• The mosque’s courtyard is the largest of all Ottoman mosques, with a striking ablution fountain in the center.
• Over 200 stained-glass windows help illuminate the interior naturally.
• Despite being centuries old, the mosque still functions as an active place of worship and is closed to tourists during the five daily prayers.
