In 1951 Ciutadella Park was declared a historic monument and is considered an open air museum
The Parc de la Ciutadella is Barcelona's most central park. The park includes a zoo, a lake, a large fountain and several museums. The Catalan Parliament is seated in a building at the center of the park.
The thirty hectare (74 acre) large park forms a green oasis close to the always crowded historic center of Barcelona. The park is laid out nicely with wide promenades, colorful flowerbeds and many palm trees.
There's much to see here: fountains and sculptures decorate the park while several interesting buildings will catch the eye of architecture buffs. There's plenty to do as well; the park's small lake is a popular spot where you can hire a rowing boat, there are several museums in the park and the zoo is always a popular attraction.
