The Parc de la Ciutadella (Catalan pronunciation: [ˈpaɾɡ də lə siwtəˈðeʎə]; "Citadel Park") is a park on the northeastern edge of Ciutat Vella, Barcelona, Catalonia, Spain. For decades following its creation in the mid-19th century, this park was the city's only green space.
The 70-acre (280,000 m2) grounds include the city zoo (once home to the albino gorilla Snowflake, who died in 2004), the Palau del Parlament de Catalunya, a small lake, museums, and a large fountain designed by Josep Fontserè (with possible contributions by the young Antoni Gaudí). In 1714, during the War of the Spanish Succession, Barcelona was laid siege for 13 months by the army of Philip V of Spain. The city fell, and in order to maintain control over it, and to prevent the Catalans from rebelling as they had in the previous century, Philip V built the citadel of Barcelona, at that time the largest fortress in Europe. A substantial part of the district it was constructed in (La Ribera) was destroyed to obtain the necessary space, leaving its inhabitants homeless. The fortress was characterized by having five corners, which gave the citadel defensive power, and by a rather wide surrounding margin, serving as location for the army's cannons.
