Formerly known as Hallicarnassus, Bodrum is the home of the great Mausoleum, one the seven wonders of antiquity, the famous castle, amphitheatre and to a very unique marine museum. Nowadays, it is Turkey's most popular seaside tourist destination, a party town with a magnificent mountain surrounding, that is full of great markets. The most impressive landmark is the Bodrum Castle, built by the Crusaders in the 15th century, overlooking the harbor and the International Marina. The castle grounds includes a Museum of Underwater Archeology and hosts several cultural festivals throughout the year. From here, you can take daytrips to the nearby islands or you can enjoy the Mavi Yoluculu (the "Blue Cruise"), Cevat's romanticized weeklong journey along the glorious coastlines of the Mediterranean.
