Tivoli Park is the largest and most beautiful park in Ljubljana, spanning over 5 square kilometers from the city center to the forested slopes of Roznik hill. Designed in 1813 by French engineer Jean Blanchard, the park features tree-lined promenades, a fish pond, botanical garden, and several cultural institutions including the International Centre of Graphic Arts in Tivoli Mansion and the Museum of Contemporary History. The Jakopic Promenade, designed by architect Joze Plecnik, serves as an open-air gallery for large photographs. The park offers tennis courts, playgrounds, a swimming pool, and winter ice skating.
