Bodrum Castle, also known as the Castle of St. Peter, is a medieval fortress located in the coastal town of Bodrum in southwestern Turkey. The castle was built by the Knights Hospitaller, a Christian military order, in the 15th century.
The castle was constructed on the site of the ancient city of Halicarnassus, which was the birthplace of the famous historian Herodotus. The Knights Hospitaller built the castle to defend against attacks by the Ottoman Empire and other enemies.
Bodrum Castle is considered to be one of the best-preserved examples of medieval architecture in the world. It has a unique shape, with a pentagonal plan and five towers at each corner. The castle is surrounded by a moat and features high walls and a number of defensive structures, including bastions and battlements.
In addition to its defensive features, Bodrum Castle also served as a residence for the Knights Hospitaller and as a center for trade and commerce in the region. Today, the castle houses the Museum of Underwater Archaeology, which contains a collection of artifacts from shipwrecks in the Aegean Sea and other underwater sites.
Overall, Bodrum Castle is an important historical and cultural landmark in Turkey and a popular tourist attraction.
