The Phoenix Park is an urban park in Dublin lying 2–4 km west of the city centre, north of the River Liffey.
Its 16 km perimeter wall encloses 707 hectares, the largest walled city park in Europe.
The residence of the President of Ireland (Áras an Uachtaráin) built in 1754 is located in the park. Originally named the Viceregal Lodge where the Lord Lieutenant lived for most of the intervening years until the creation of the Irish Free State in 1922.
Dublin Zoo is one of Dublin’s main attractions.
It houses more than 700 animals and tropical birds from around the world and was founded in 1830 and opened to the public on 1 September 1831, with animals from the London Society, making it the third oldest zoo in the world.
Within a year the zoo housed 123 species.
