|Rumelihisarı, Istanbul, Turkey|
|Built by||Mehmed II|
|Battles/wars||Fall of Constantinople|
Rumelihisarı (also known as Rumelian Castle and Roumeli Hissar Castle) or Boğazkesen Castle (literally meaning "the Strait-Cutter Castle") is a medieval fortress located in the Sarıyer district of Istanbul, Turkey, on a series of hills on the European banks of the Bosphorus. The fortress also lends its name to the immediate neighborhood around it.
Conceived and built between 1451 and 1452 on the orders of Ottoman Sultan Mehmed II, the complex was commissioned in preparation for the Ottoman conquest of Constantinople in 1453 to cut off any potential maritime military or logistical relief that may have come to the Byzantine Empire's aid by way of the Bosphorus Strait, hence the fortress's alternative name, "Boğazkesen", i.e. "Strait-cutter" Castle. Its older sister structure, Anadoluhisari ("Anatolian Fortress"), sits on the opposite banks of the Bosporus, and the two fortresses worked in tandem in 1453 to throttle all maritime traffic along the Bosphorus, thus helping the Ottomans achieve their goal of making the city of Constantinople (later renamed Istanbul) their new imperial capital.
After the conquest of the city, Rumelihisarı served as a customs checkpoint and occasional prison, notably for the embassies of states that were at war with the Empire. After suffering extensive damage in the great earthquake of 1509, the structure was repaired, and was used continuously until the late 19th century.
Today, the fortress is a popular museum open to the public, and further acts as an open-air venue for seasonal concerts, art festivals, and special events.
The necessity of a strategic fortress on the Bosphorus was well-known to the Ottomans, who had started in the late 14th century to harbor intentions of capturing the city of Constantinople as a new capital to their fledgling Empire. In a previous Ottoman attempt to conquer the city, Sultan Murad II (1404–1451) had encountered difficulties due to a blockade of the Bosphorus by the Byzantine fleet. Having learned the imporance of maritime strategy from this earlier attempt, Sultan Mehmed II (1432–1481), son of Murad II, started planning and design work on the fortress immediately following his ascent to the throne in 1451. Mehmed further refused the offer of peace proffered by the Byzantine Emperor Constantine XI (1404–1453), who understood the young Sultan's intentions and his plans for the conquest of the city.
Mehmed quickly commissioned the contruction of a large fortress that would be used to control all sea traffic on the Bosphorus strait and would work together with the older Anadoluhisari (Anatolia Fortress) to prevent any possible aid from the Black Sea from reaching Constantinople during the planned Turkish siege of the city in 1453, particularly from Genoese colonies such as Caffa, Sinop and Amasra.
The site for the new fortress was quickly decided to be the narrowmost point of the Bosphorus, where the strait is a mere 660 meters (2,170 ft). This tall, hilltop site on the strait's European banks not only made for easier control of the waterway, but also had the advantage of being situated directly across the Anadoluhisarı ("Anatolian Fortress") on the Anatolian (i.e. Asian) banks of the Bosphorus; an older Ottoman fortress that was built between 1393 and 1394 by Sultan Bayezid I. Historically, there had been a Roman fortification at the hilltop where Rumelihisari was to be built, which had later been used as a prison by the Byzantines and Genoese. Later on, a monastery had been built there.
Construction began on April 15, 1452. Each one of the three main towers was named after the royal vizier who supervised its respective construction; Sadrazam Çandarlı Halil Pasha, who built the large tower next to the gate; Zağanos Pasha, who built the south tower; and Sarıca Pasha, who built the north tower. The Sultan himself personally inspected the activities on the site.
With the help of thousands of masons and workers, the fortress was completed in a record time of 4 months and 16 days on August 31, 1452. According to popular lore, in order to encourage his builders to work faster, the Sultan designed the fortress's layout in the shape of the name of the Muslim prophet Muhammed in Arabic script when read from above. As Muhammad and Mehmed share the same Arabic spelling (محمد), it is likely that this act was also made as an homage to himself.
The Rumelihisarı fortification has one small tower, three main towers, and thirteen small watchtowers placed on the walls connecting the main towers. One watchtower is in the form of a quadrangular prism, six watchtowers are shaped as prisms with multiple corners and six others are cylindrical. The main tower in the north, the Saruca Pasha Tower, is in cylindrical form with its 9 stories and height of 28 m (92 ft), has a diameter of 23.30 m (76.4 ft) and its walls are 7 m (23 ft) thick. Today, this tower is called the Fatih (Conqueror) Tower after Sultan Mehmed II. Halil Pasha Tower, a dodecagon prism, which stands at the waterfront in the middle of the fortress, has also 9 stories. It is 22 m (72 ft) high with a 23.30 m (76.4 ft) diameter and the walls are 6.50 m (21.3 ft) thick. The main tower in the south, the Zağanos Pasha Tower, has only 8 stories. The cylindrical tower is 21 m (69 ft) high, has a 26.70 m (87.6 ft) diameter with 5.70 m (18.7 ft) thick walls. The space within each tower was divided up with wooden floors, each equipped with a furnace. Conical wooden roofs covered with lead crowned the towers. The outer curtain walls of the fortress are from north to south 250 m (820 ft) long and from east to west varying between 50 and 125 m (164 and 410 ft) long. Its total area is 31,250 m2 (336,372 sq ft).
The fortress had three main gates next to the main towers, one side gate and two secret gates for the arsenal and food cellars next to the southern tower. There were wooden houses for the soldiers and a small mosque, endowed by the Sultan at the time of construction. Only the minaret shaft remains of the original mosque, while the small masjid added in the mid-16th century has not survived. Water was supplied to the fortress from a large cistern underneath the mosque and distributed through three wall-fountains, of which only one has remained. Two inscriptive plaques are found attached on the walls.
The fortress, designed by architect Müslihiddin, was initially called "Boğazkesen", literally meaning "The Strait Cutter", referring to the Bosporus Strait. The name carries a secondary and more macabre meaning; as boğaz not only means strait but also "throat" in Turkish.
It was later renamed as Rumelihisarı, which means "Fortress on the Land of the Romans", i.e. Byzantine Europe, or the Balkan peninsula.
Usage in the past
A battalion of 400 Janissaries were stationed in the fortress, and large cannons were placed in the Halil Pasha Tower, the main tower on the waterfront. Having completed his fortresses, Mehmed proceeded to levy a toll on ships passing within reach of their cannon. A Venetian vessel ignoring signals to stop was sunk with a single shot and all the surviving sailors beheaded, except for the captain, who was impaled and mounted as a human scarecrow as a warning to further sailors on the strait. These cannons were later used until the second half of the 19th century to greet the sultan when he passed by sea.
After the fall of Constantinople, the fortress served as a customs checkpoint. Rumelihisarı, which was designated to control the passage of ships through the strait, eventually lost its strategic importance when a second pair of fortresses was built further up the Bosphorus, where the strait meets the Black Sea. In the 17th century, it was used as a prison, primarily for foreign prisoners of war. Rumelihisarı was partly destroyed by an earthquake in 1509, but was repaired soon after. In 1746, a fire destroyed all the wooden parts in two of the main towers. The fortress was repaired by Sultan Selim III (1761–1807). However, a new residential neighborhood was formed inside the fortress after it was abandoned in the 19th century.
In 1953, on the orders of President Celal Bayar, the inhabitants were relocated and extensive restoration work began on 16 May 1955, which lasted until 29 May 1958. Since 1960 Rumelihisarı has been a museum and an open-air theater for various concerts at festivals during the summer months.
The Fatih Sultan Mehmet Bridge which spans the Bosporus is located close to the fortress, to the north.
Rumelihisarı is open to public every day except Wednesdays from 9:00 to 16:30.
The fortress was depicted on various Turkish banknotes during 1939-1986.
