If you are a diver who enjoys exploring underwater shipwrecks, here is one more place to add to your list, Gallipoli Historical Underwater Park beneath the Dardanelles Strait in Turkey.
Back in 1973, Turkey created the Gelibolu (Gallipoli) Peninsula Historical National Park at the southern end of the Gallipoli Peninsula to honor the 500,000 soldiers who lost their lives in this region in a prolonged battle between the Ottoman and the Allied forces in the First World War. The latter was forced to retreat and according to historians it was this battle which sowed the seeds of Turkish nationalism.
