In the northern part of the iSimangaliso Wetland Park you will find Kosi Bay. It has an interesting history and even today it is unique.
St. Lucia was first named in 1554 as "Rio de la Medaos do Oura" ("River of the Dows of Gold") by the survivors of the Portuguese ship Saint Benedict. At this stage, only the Tugela River mouth was known as St. Lucia. Later, in 1575, the Tugela River was named Tugela. On 13 December 1575, the day of the feast of Saint Lucy, Manuel Peresterello renamed the mouth area to Santa Lucia.
In 1822, St. Lucia was proclaimed by the British as a township.
In 1895, St. Lucia Game Reserve, 30 km north of the town was proclaimed.
In 1971, St. Lucia Lake and the turtle beaches and coral reefs of Maputaland have been listed by the Convention on Wetlands of International Importance (Ramsar Convention).
In December 1999, the park was declared a UNESCO World Heritage Site.
The park was previously known as the Greater St. Lucia Wetland Park, but was renamed effective from 1 November 2007. The word 'isimangaliso' is Zulu for 'a miracle'
