Khortytsia is the largest island in the River Dnieper, and is 12.5 kilometres long and up to 2.5 kilometres wide. The island forms part of the Khortytsya National Park. This historic site is located within the city limits of Zaporizhia, Ukraine.
The island has played an important role in the history of Ukraine, specially in the history of the Zaporozhian Cossacks. The island has unique flora and fauna, including oak groves, spruce woods, meadows, and steppe. The northern part of the island is very rocky and high (rising 30 m (98 ft) above the river bed) in comparison to the southern part, which is low, and often flooded by the waters of the Dnieper.
The earliest record about a stronghold known as a sich refers to the one was located on the island of Small Khortytsia and was established by the Volhynian prince Dmytro Vyshnevetsky. The Small Khortytsia Island is 20 times smaller than Khortytsia itself.
It was here that politically important decisions were made that influenced the course of history.
