A Journey Through Time: The Origins of Sultanahmet Square

The story of Sultanahmet Square is a story of transformation. Its foundations are much older than the Ottoman mosques that dominate it today. To understand its importance, we must first travel back to a time when Istanbul was Constantinople, the capital of the Byzantine Empire.

From Byzantium’s Hippodrome to an Ottoman Center

Long before it was known as Sultanahmet Square, this area was the legendary Hippodrome of Constantinople. Built by the Roman Emperor Septimius Severus in 203 AD and later enlarged by Constantine the Great, the Hippodrome was the epicentre of the city’s social and sporting life.

• A Stage for Spectacle: This U-shaped stadium was colossal, estimated to hold up to 100,000 spectators. The main events were the thrilling and often violent chariot races between two main factions, the Blues (Venetoi) and the Greens (Prasinoi). These weren’t just sporting teams; they represented political, social, and religious divisions within the city.
• The Spina: The central barrier of the Hippodrome, known as the spina, was adorned with magnificent monuments brought from all corners of the empire to showcase its power and wealth. Remarkably, some of these ancient treasures still stand in Sultanahmet Square today.
• More Than Just Games: The Hippodrome was also a political stage. Emperors were crowned here, military victories were celebrated with triumphant parades, and public executions were carried out. It was here, during the infamous Nika Riots of 532 AD, that tens of thousands were killed, nearly costing Emperor Justinian I his throne.

When the Ottoman sultan Mehmed the Conqueror took Constantinople in 1453, the Hippodrome was already in ruins, having been looted during the Fourth Crusade in 1204. However, the Ottomans recognized the historical and strategic importance of the area. They did not rebuild the stadium, but instead repurposed the large space, which they called At Meydanı (Horse Square), preserving it as the nerve center of imperial life.

The Architectural Jewels of Sultanahmet Square

Today, Sultanahmet Square is defined by the monumental structures that frame it. Each building and monument tells a unique chapter of Istanbul’s layered history, creating a skyline that is recognized across the globe.

The Blue Mosque (Sultan Ahmed Mosque): A Symphony in Blue

Directly facing Hagia Sophia is the majestic Sultan Ahmed Mosque, popularly known as the Blue Mosque. Commissioned by the young Sultan Ahmed I and completed in 1616, its purpose was to reassert Ottoman power and create a monument that could rival the grandeur of the Hagia Sophia.

• Architectural Marvel: Designed by Sedefkâr Mehmed Ağa, the mosque is a masterpiece of classical Ottoman architecture. Its most distinctive features are its six slender minarets, a unique design that caused controversy at the time as only the Grand Mosque in Mecca had six.
• The Iznik Tiles: The mosque earns its nickname from the more than 20,000 handmade blue Iznik ceramic tiles that adorn its interior walls. These tiles, featuring intricate floral and geometric patterns, create a breathtaking visual effect, bathing the interior in a cool, ethereal blue light.
• A Place of Worship: As a functioning mosque, it offers visitors a glimpse into the spiritual heart of the city. Remember to dress modestly (covering shoulders and knees) and women should cover their hair before entering.

Hagia Sophia: A Dome That Changed History

The undisputed queen of Sultanahmet Square is the Hagia Sophia (Ayasofya). Its history is a powerful symbol of Istanbul’s own complex identity.

1. Byzantine Cathedral: Consecrated in 537 AD under Emperor Justinian I, it was the largest Christian church in the world for nearly a thousand years. Its massive dome was a revolutionary architectural achievement that was said to have “changed the history of architecture.”
2. Ottoman Mosque: After the 1453 conquest, Sultan Mehmed II converted Hagia Sophia into an imperial mosque. Minarets were added to its exterior, and its Christian mosaics were covered with plaster.
3. Secular Museum: In 1935, Mustafa Kemal Atatürk, the founder of the modern Turkish Republic, transformed it into a museum, a symbol of a new, secular Turkey.
4. Reverted to a Mosque: In 2020, it was reconverted into a functioning mosque, a decision that remains a topic of international discussion.

Visiting Hagia Sophia is a profound experience, where you can see the seamless, and sometimes jarring, blend of Christian iconography and Islamic calligraphy under one magnificent dome.

The Silent Witnesses: Monuments of the Hippodrome

Walking through the central park of Sultanahmet Square, you are walking along the ancient spina of the Hippodrome. Three ancient monuments have survived the ravages of time:

• The Obelisk of Theodosius: This is the oldest monument in Istanbul. Carved in Egypt around 1500 BC, this pink granite obelisk was brought from the Temple of Karnak in Luxor to Constantinople by Emperor Theodosius I in 390 AD. The marble base features intricate carvings depicting the emperor and his family watching the chariot races.
• The Serpent Column: Forged from the melted-down shields of defeated Persian soldiers after the Battle of Plataea in 479 BC, this bronze column was a gift to the Temple of Apollo at Delphi. It originally depicted three intertwined serpents whose heads supported a golden bowl. The column was moved here by Constantine the Great. The heads were lost over the centuries, though one is on display in the nearby Istanbul Archaeology Museums.
• The German Fountain: The newest addition to the square, this ornate, octagonal fountain was a gift from German Emperor Kaiser Wilhelm II to Sultan Abdülhamid II in 1898 to commemorate the Emperor’s visit. Its beautiful neo-Byzantine style and golden mosaics stand in contrast to the more ancient monuments.
