Where to even start with Bodrum Castle? It has the most convoluted, Da Vinci Code-style history.
Today, the castle is a historical museum as well as the Museum of Underwater Archaeology. It sits right in the middle of Bodrum's harbors with an amazing view of the Aegean Sea that will have even the most seasick ready to join up with pirates.
Mausoleum at Halicarnassus - one of the original seven wonders of the world. Which explains where those stones went! The Christian military order, Knights Hospitaller, built the castle along with a couple other fortifications in Rhodes and Kos. They even had the Pope guarantee entry to heaven for all the workers during construction.
Each of the countries involved with the Knights got their own section of the castle. There are German, French and Italian towers. The British tower looks like it was flown straight in from England, complete with big fireplaces, suits of armor and cozy nooks.
