The Cape Planka (Croatian: Rt Ploča, Punta Planka) is a cape of Croatian shore of the Adriatic Sea located 2 kilometres (1.2 mi) southeast of village of Rogoznica in the Šibenik-Knin County. The cape is the most prominent point of land along the Dalmatian shore. It represents a geographic and climatological boundary of the northern and the southern Adriatic often characterised by strong sea currents and swells as weather systems from the north and the south come in contact. There is a navigational beacon at the cape.[1]
In Classical Antiquity, the cape was named after Diomedes who said to have sailed to that point of the coast. The cape is known as a hazardous point in navigation and there are several shipwrecks in the vicinity. There is a legend of a miracle attributed to the bishop of the Roman Catholic Diocese of Tragurium and later a Christian saint, John of Trogir. He is said to have saved Coloman, King of Hungary from death in a shipwreck off the Cape Planka by walking on the surface of the sea. A votive church has been completed to commemorate the miracle on the cape in 1324.[1]
The Cape Planka was the southernmost point of the eastern Adriatic coast promised to the Kingdom of Italy by the Triple Entente during the World War I through the 1915 Treaty of London in return for Italian entry into the war.[2]
