10 Parks In Dublin City You Need To Visit Before You Die
"Although not essentially a park however it is well deserved to be on this list. Established in 1831, this is the third-oldest zoo in the world (after London and Paris), nestled in the midst of the city’s largest playground, the Phoenix Park, about 3km (2M) west of the city centre. This 12-hectare (30 acre) zoo provides a naturally landscaped habitat for more than 235 species of wild animals and tropical birds."
