Eyüp Sultan Mosque

Listen first. Somewhere close, wings beat against the air as a flock of pigeons lifts from the courtyard stones. A child laughs. A low murmur of prayer drifts from an open window. The paving under your feet is smooth and pale, worn down by centuries of slow, careful footsteps. Before you look at any dome or minaret, notice the mood here. People do not rush. They come to this place on purpose, and many of them come with something on their mind.

You are standing at Eyüp Sultan Mosque, at the far upper end of the Golden Horn. This is outside the old land walls of Constantinople, beyond the city that the Byzantine emperors once defended. For many Muslims in Istanbul, and far beyond Turkey, this is the most sacred spot in the city. The reason is not the mosque itself. The reason is a man who died here long before any Ottoman ever arrived.

His name was Abu Ayyub al-Ansari. In Turkish, he is called Eyüp Sultan, and the whole district carries his name. He was a companion of the Prophet Muhammad. When the Prophet first arrived in Medina, it was Abu Ayyub who welcomed him into his own home. That act of hospitality made him one of the most honoured figures in early Islam. Decades later, as a very old man, he joined an Arab army that marched all the way to the walls of Constantinople.

That siege took place in the seventh century, and it failed. The city held. Abu Ayyub fell ill and died during the campaign. According to the traditional accounts, he asked to be buried as close to the walls as his companions could carry him. So here he stayed, in foreign ground, outside a Christian capital. For roughly eight hundred years, the city around his grave remained Byzantine.

Then came 1453. Sultan Mehmed the Second, the young Ottoman ruler who conquered Constantinople, wanted to honour the companion who had come so far. Here the story moves into tradition. Legend has it that Mehmed's spiritual teacher, a scholar named Akşemseddin, located the forgotten grave through a dream or a vision. Historians treat this part as pious tale rather than proven fact. What is certain is that a tomb was built over the site, and a mosque rose beside it a few years later.

That makes this the first great mosque the Ottomans built in Istanbul after the conquest. Think about that for a moment. Before Süleymaniye, before the Blue Mosque, before almost every skyline you know from postcards... there was this complex, out here by the water. Mehmed chose to start his new city not in its centre, but at the grave of a guest who had come centuries too early.

The building in front of you, however, is not Mehmed's original. Earthquakes badly damaged the first mosque in the eighteenth century. Sultan Selim the Third had it rebuilt, and the work was finished around the end of that century. So what you see is a late Ottoman building, lighter and more decorative than the heavy early style. Look for the softer curves, the ornamental details, and the brighter, airier feel inside. This was a period when Ottoman architects borrowed ideas from European Baroque, the curving, ornate style of that time.

Here is something many visitors miss. For centuries, this mosque played a role in every new reign. Ottoman sultans did not have a coronation with a crown. Instead, each new sultan came here to be girded with a sword — traditionally linked to Osman, the founder of the dynasty. The ceremony tied the new ruler to the very beginning of the Ottoman story, and to the holy companion buried a few steps away. Every sultan, from the sixteenth century onward, began his rule at this courtyard.

Now turn toward the tomb itself. It stands across the courtyard from the mosque, and the line of people outside it tells you where to go. The walls of the tomb are covered with tiles from Iznik, the town famous for Ottoman ceramics. They come from different periods, so the blues, turquoises and reds do not all match. That patchwork is honest. It shows generations of sultans and donors adding their own offering over time. Visitors pause at the silver-framed window, raise their hands, and pray quietly.

Spend a little time simply watching the people around you. On many days, you may see young boys dressed like little princes, in white satin capes and caps trimmed with feathers. They are about to be circumcised, an important rite of passage in Turkish families, and a visit here is part of the celebration. You may also see newly married couples, grandmothers with prayer beads, and families who have travelled from other countries. This is a living shrine, not a museum.

Above the mosque, the hillside fills with gravestones. Being buried near Abu Ayyub was considered a great blessing, so for centuries Ottoman officials, scholars and ordinary families chose this ground. Many of the old stones are topped with carved turbans or fezzes. The shape of the headgear once showed the rank or profession of the person buried below. Women's stones often carry carved flowers instead. Walking among them is like reading a quiet record of Ottoman society.

If you climb that hill, by foot along the cemetery paths or by the small cable car, you reach a famous terrace café. It is named after Pierre Loti, a French writer and naval officer who loved Istanbul in the late nineteenth century. From up there, the whole Golden Horn opens below you. You can see the long, narrow inlet of water curving toward the old city, with the domes and minarets of the historic peninsula on the horizon.

Back down here, take one last look around. The pigeons settle again on the stones. The water of the Golden Horn lies just beyond the rooftops. Somewhere a vendor calls out, selling rosaries or simit, the round sesame bread. Everything in this place began with one old man who travelled very far, and one young sultan who decided to remember him. As you walk away, listen for the call to prayer — it has rung from this spot for more than five hundred years.
