Anyone would think that having been home to one of the seven wonders of the ancient world, that the Halicarnassus Mausoleum would be the pinnacle historical tour of Bodrum, yet the star of the show is Bodrum Castle. Also known as the Castle of Saint Peter, and built in 1406 by the Knights of Saint John, it was a defence port and jail, before becoming a storeroom in the 1960s for sponge divers. These days it is more of an iconic landmark, a testament to the history of the region and home to the underwater museum displaying old shipwrecks such as the Bronze Age, Uluburun.
