Introduction
Parc de la Ciutadella is Barcelona's oldest and largest public park, located on the northeastern edge of Ciutat Vella, built on the site of a former military fortress ahead of the 1888 Universal Exposition. It features the Cascada Monumental fountain, a boating lake, the city zoo, the Catalan regional parliament building, and 19th-century structures now used as museums, making it a popular spot for picnics, walks, and relaxation.
