Rumeli Fortress in Istanbul: History and Visitor Guide

Rumeli Fortress (Rumeli Hisarı) is one of the most striking landmarks on the Bosphorus. Sultan Mehmed II built it in 1452, the year before the conquest of Constantinople, to control the strait and cut off help reaching the Byzantine capital from the Black Sea. Tradition says it went up in only around 90 days.

Today the fortress is a museum and one of the best viewpoints over the Bosphorus.

History of Rumeli Fortress

Mehmed II chose the narrowest point of the Bosphorus, where Europe and Asia are only around 700 metres apart. On the opposite shore stood Anadolu Fortress (Anadolu Hisarı), built by his great-grandfather Bayezid I in the 1390s. With cannons on both sides, the Ottomans could stop any ship passing through, which is why the fortress was also called Boğazkesen, "the cutter of the strait".

Thousands of workers built it at remarkable speed. Each of the three main towers was entrusted to one of the sultan's viziers, Saruca Pasha, Halil Pasha and Zağanos Pasha, and they are still named after them. Inside the walls there was also a small mosque for the garrison; only the base of its minaret survives. Once Constantinople fell in 1453, the fortress lost its military role and was later used as a customs post and a prison.

What to see at Rumeli Fortress

• The three great towers and the curtain walls climbing the hillside.
• Ottoman cannons and cannonballs displayed in the grounds.
• Views of the Bosphorus and the Fatih Sultan Mehmet Bridge from the walls and terraces.
• The open-air amphitheatre inside the walls, where summer concerts were once held.

For photographers, it is one of the best places to take panoramic pictures of the Bosphorus. The museum has also displayed links said to come from the great chain that once closed the Golden Horn.

The legend of the fortress's shape

Seen from above, the outline of the fortress is said to resemble the name Muhammad written in Arabic script. According to the story, Mehmed II believed that military strength alone would not be enough to take and protect the city, and wanted the spiritual support of the Prophet's name. Historians debate the claim, but it remains one of the best-loved legends of the Bosphorus.

Visiting Rumeli Fortress

The fortress is in Sarıyer district, on the coast road between Bebek and the Fatih Sultan Mehmet Bridge. Buses run along the shore from Beşiktaş and Kabataş, and from Bebek it is a pleasant waterside walk. The fortress has been through long restoration work in recent years, so check that it is open, and the current fees and hours, on the official museum website before you go.

Tips for your visit

• Wear good shoes: paths and stairs on the walls are steep and uneven.
• Go late in the afternoon for the best light over the water.
• Combine it with a walk through Bebek or Arnavutköy and tea by the Bosphorus.

Seeing Rumeli Fortress from the Bosphorus

The fortress looks most dramatic from the water, with its towers rising above the shore and Anadolu Fortress facing it across the strait. Both fortresses are highlights of any cruise along the Bosphorus Strait; see our guide to Bosphorus cruises in Istanbul for the options.

The stretch of shore around the fortress is also lined with historic waterfront mansions (yalı) on both sides, from Bebek and Arnavutköy to Kandilli and Anadoluhisarı. The Bosphorus mansions cruise focuses on this part of the strait.

On a private Bosphorus yacht cruise, you can ask the captain to slow down in front of the fortress for photos, and board at nearby piers such as Bebek or Kuruçeşme.
