Rumeli Hisarı: the Bosphorus Fortress
The castle Mehmed II built in 1452, a year before the conquest of Constantinople
In short: Rumeli Hisarı (the Rumelian Castle) is the great Ottoman fortress on the European shore of the Bosphorus, built by Sultan Mehmed II in 1452. It is currently closed to visitors for restoration, and no reopening date has been announced. You can still see it well from the shore road, from the waterfront in Bebek and from a Bosphorus boat trip.
Last checked: 11 November 2026. Reports from September 2026 say the fortress has been closed for restoration for about six and a half years. Some official listings still show opening hours, but these are out of date.
The “Strait-cutter”
Mehmed II built the fortress in a few months in 1452, to control shipping on the Bosphorus before his siege of Constantinople the following year. That is why it was also called Boğazkesen, the “Strait-cutter”. It stands at the narrowest part of the strait, directly opposite the older fortress of Anadolu Hisarı on the Asian shore.
Its three great towers are named after the viziers who were responsible for building them:
- Saruca Pasha Tower: the tallest, about 28 metres, at the northern end.
- Halil Pasha Tower: about 22 metres, by the water.
- Zağanos Pasha Tower: about 21 metres, at the southern end.
After the conquest the fortress lost its military role and was used for centuries as a prison. It was damaged by fire in 1746 and repaired under Selim III, and it was restored in the 1950s, around the 500th anniversary of the conquest. Today it is a museum.
Can you visit now?
Not inside. The fortress has been closed since around 2020 for a restoration run by Istanbul Metropolitan Municipality, and a reopening planned for 2023 did not happen. When it reopens it will again be a Ministry of Culture museum, and foreign visitors will pay an entry fee. Until then, these are the best ways to see it:
- From a Bosphorus boat: the fortress is one of the highlights of any Bosphorus cruise, together with Anadolu Hisarı opposite.
- From the shore road: the walls rise straight up from the coast road between Bebek and the Fatih Sultan Mehmet Bridge.
- From Bebek: walk north along the waterfront from Bebek, about 1.5 km.
Getting there
- By bus: buses run along the Bosphorus coast road from Kabataş and Beşiktaş to the “Rumelihisarı” stop. Check current routes on the IETT site or app.
- By ferry: the Rumelihisarı pier is a few minutes’ walk away, but not all Bosphorus lines call there; check Şehir Hatları timetables.
- Paying: use your Istanbulkart. See getting around Istanbul.
