a round bastion to strengthen the land side of the fortress. Sir Thomas Docwra was appointed Captain of the Castle in 1499. Despite their extensive fortifications, the Crusaders's towers were no match for the forces of Suleiman the Magnificent, who overpowered the knights in 1523 and captured the castle. Under the Ottoman rule, the castle's importance waned, and in 1895 it was converted into a prison. 16th century Between 1505 and 1507 the few sculptures from the mausoleum that had not been smashed and burnt for lime were integrated into the castle for decoration. These included twelve slabs of the Amazonomachy (combat between Amazons and Greeks) and a single block of the Centauromachy, a few standing lions, and one running leopard. When faced with an attack from Sultan Suleiman, Philippe Villiers de L'Isle-Adam, the Grand Master of the Knights Hospitallers, ordered the Castle to be strengthened again. Much of the remaining portions of the mausoleum were broken up and used as building material to fortify the castle. By 1522 almost every block of the mausoleum had been removed. In June 1522 the sultan attacked the Order's headquarters in Rhodes from the Bay of Marmaris with 200,000 soldiers (Siege of Rhodes (1522)). The castle of Rhodes fell in December 1522. The terms of surrender included the handing over of the Knights' fortresses in Kos and St Peter's Castle in Bodrum. After the surrender, the chapel was converted into a mosque and a minaret was added. This mosque was called the Süleymaniye Camii, as attested by a traveler, Evliya Chelebi, who visited Bodrum in 1671. The minaret was destroyed on 26 May 1915 by rounds fired by a French warship during World War I. It was reconstructed in its original shape in 1997. 19th century In 1846 Lord Canning, HM Ambassador to Constantinople, obtained permission to remove twelve marble reliefs showing a combat between Greeks and Amazons from the castle. Sir Charles Newton, a member of the staff of the British Museum, conducted excavations and removed a number of stone lions and one leopard in 1856. These are all still to be found today at the British Museum. In later years, the castle has been used for different purposes. It was used as a military base by the Turkish Army during the Greek Revolt in 1824. In the 19th century, the chapel which had been converted for use as a mosque had
