Bodrum is a city located on the Bodrum Peninsula, extending from Turkey's southwest coast into the Aegean Sea. The city is known for its twin bays, offering stunning views of Bodrum Castle, a medieval fortress constructed partly with stones from the Mausoleum at Halicarnassus, one of the Seven Wonders of the Ancient World, completed in the 4th century B.C. Bodrum also serves as a gateway to nearby beach towns and resorts.
