The Cayenne Festival is observed in Cayenne, the capital city of French Guiana, every October 15. This festival serves as the official holiday for the city and celebrates Guyanese culture through various festive events, including pageants, fairs, concerts, and dance parties held throughout the month of October. The festival highlights the rich history of French Guiana, which was first settled by the French in the 17th century after earlier attempts by other European powers. Notable locations in Cayenne, such as the Place des Palmistes, the Botanical Garden, and the Saint-Sauveur Cathedral, serve as key sites for the celebrations. It is important to note that the Cayenne Festival should not be confused with the Cayenne Carnival, which occurs annually in January and February. The festival is a vibrant reflection of the local culture and heritage.
