Bodrum Castle

Bodrum Castle (Turkish: Bodrum Kalesi) is a historical fortification located in southwest Turkey in the port city of Bodrum, built from 1402 onwards, by the Knights of St John (Knights Hospitaller) as the Castle of St. Peter or Petronium. A transnational effort, it has four towers known as the English, French, German, and Italian towers, bearing the names of the nations responsible for their construction. The chapel was built by the knights and the first walls completed in due course. The castle started reconstruction later, only to be taken over by the Islamic Ottoman Empire subsequently. The chapel was converted to a mosque, and a minaret was added. The castle remained under the empire for a long period. After remaining empty following World War I, in the early 1960s, the castle became the home for the Bodrum Museum of Underwater Archaeology. It is inscribed in the UNESCO Tentative list of World Heritage Sites in Turkey. It is located in Muğla, Türkiye.
