The '' is a park on the northeastern edge of Ciutat Vella, Barcelona, Catalonia. For decades following its creation in the mid-19th century, this park was the city's only green space. The 70acre grounds include the city zoo, the Parliament of Catalonia, a small lake, museums, and a large fountain designed by Josep Fontserè .The main attraction was, from its establishment, the zoo. This was due to out of the 7,000 animals present. Near the zoo's entrance, a climbable gigantic stone mammoth is to be seen, as is a metallic cat in another area of the park.One half of the park's paths are sinuous and rather natural seeming trails, and the other half ordered and parallel. Along both, huge a variety of vegetation is displayed.LocationsCitadelIn 1714, after a 13-month siege, Barcelona fell to the army of Philip V of Spain. In order to maintain control over the city, and to prevent the Catalans from rebelling as they had in the previous century, King 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 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. It included enough buildings to house 8,000 people.Hundreds of Catalonians were forced to work on the construction for three years, while the rest of the city provided financial backing for this and for warfare-related expenses as well, with a new tax named el cadestre. Three decades later a quarter was rebuilt around the fortress named Barceloneta, which is located inside the neighborhood Ciutat Vella.
