CASTLES ON THE BOSPHORUS AND ÇANAKKALE STRAITS

The castles of Anadolu Hisarı and Rumeli Hisarı on the Bosphorus.

 

Since antiquity the Bosphorus and Çanakkale Straits which link the Black Sea to the Mediterranean via the Marmara Sea have been of crucial strategic importance, and in Ottoman times four pairs of castles were built on these straits at the narrowest points. From these cannon could be fired from both the European and Asian shores, so preventing the pas­sage of enemy warships.
 

Construction of Rumeli Hisarı began in 1452

The castle at the southernmost point of the Gelibolu (Gallipoli) peninsular was called Seddülbahir, and facing it on the Asian shore, overlooking the Plain of Troy, was Kumkale. Both castles were built in 1656 by Grand Vezir Koprülü Mehmed Paşa after the Venetians blockaded Çanakkale Strait and captured the islands of Bozcaada (Tenedos) and Limni (Lemnos) as a countermeasure in the tug of war for Crete. The Ottomans had been attempting to seize Crete from the Venetians since 1645, but only after the castles had been built was the Ottoman navy able to first raise the blockade and regain possession of Bozcaada and Limni, and then in 1669 conquer Crete.


Both castles can be seen in a painting by an Ottoman artist depicting a battle between the Ottoman and Venetian navies. The painting is in an album in the Correr Museum in Venice.

The other two castles on Çanakkale Strait are Kilitbahir on the European shore and Kale-i Sultaniye on the Asian shore, both built by Sultan Mehmed II (1451-1481) and later reno­vated by Sultan Suleyman the Magnificent in the 16th centu­ry. Kale-i Sultaniye has been known by several other names. including Bogaz, c;imenlik and c;anakkale. The keep of Kilitbahir was in the form of a three-leaf clover. and the outer ramparts were also reminis­cent of a clover leaf. The walls of the keep rose from the water's edge. Kale-i Sultaniye was quadri­lateral in plan and encircled by moats.
 

The castles of Anadolu Hisan and Rumeli Hisan on the Bosphorus are both still standing today. The for­mer was built on the Asian shore at the narrowest point by Sultan Bayezid I (1389-1402) half a century before the conquest of Istanbul in 1453 as a means of controlling ships passing through the strait, while Rumeli Hisan was built in 1452 by Sultan Mehmed II, who at the same time increased the strength of Anadolu Hisan by building additional towers and walls with battlements and loopholes. Anadolu Hisan originally contained a mosque and a prayer terrace. In the 19th century the sea along the shore in front of the castle was filled in and wooden hous­es built on the reclaimed land.

Rumeli Hisan, also known as Yeni Hisar or Güzel Hisar, was completed in just four months, and following the conquest of Istanbul additional towers with conical roofs were built on the landward side and used as a prison.

The castles of Kilitbahir and Kale-i Sultaniye on the Çanakkale Strait can be seen in the upper and lower parts of the picture respectively


Executions were also carried out here, and the castle became known as the Black Tower. The 17th century writer Evliya Çelebi records that inside the walls was a mosque named Fatih Mosque after Mehmet the Conqueror, 180 houses providing lodging for the soldiers of the garrison, two smaller mosques and two granaries. The village outside the walls on the seaward side consisted of I 060 houses, three mosques, eleven mescits, seven schools, one public bath and 200 shops. The houses inside the walls have long since been swept away, but the mosque remains.
 

This painting by an Ottoman artist in the Correr Museum in Venice depicting the battle between the Ottoman and Venetian navies at Çanakkale shows the castles of Kumkale and Seddülbahir on the narrowest part of the strait

An 18th century miniature painting in Topkapı Palace depicts both of these Bosphorus castles, and another in the Museum of Turkish and Islamic Art depicts Rumeli Castle, In the British Museum in London there is a third minia­ture painting showing both castles, but the artist has relied rather on his imagi­nation than observation, since the architecture is English in character and they are wrongly positioned. A fourth miniature showing both castles is in the Walters Art Gallery in Baltimore.

Sultan Murad IV (1623-1640) built two more castles at the northern mouth of the Bosphorus where the strait flows into the Black Sea, Although no trace remains of that on the European shore, the extensive ruins of the other can still be seen at Anadolu Kavağı.

 

 The sole known picture of these two castles before they fell into ruins is in the abovemen­tioned album in the Correr Museum in Venice. Evliya Çelebi tells us that the quadri­lateral castle at Rumeli Kavagl measured 300 metres across and that there were sixty houses for the soldiers of the garrison and a hundred can­non inside its walls. The castle facing it on the opposite shore at Anadolu Kavagl was also quadrilateral, measuring 240 metres across and with walls 20 m in height It con­tained eighty houses to accommodate the garrison and one hundred cannon.

The French artillery engineer François Baron de Tott, who arrived in Turkey in 1755, supervised some additions to the castles on the Bosphorus, and in Ino strengthened two of the castles on Çanakkale Strait.

The castles of Rumeli Kavağı and
Anadolu Kavağı at the northern end of the Bosphorus. Only the latter survives today.
