Phoenix Park in Dublin, Ireland

The Phoenix Park is the largest enclosed urban public park in Europe located 3 km to the north west of Dublin city centre in. It measures 712 hectares (1,760 acres), with a walled circumference of 16 km that contains large areas of grassland and tree-lined avenues. The park has been home to a herd of wild Fallow deer since the seventeenth century. The name is a corruption of the Irish fionn uisce meaning "clear water".

Unusually for North Dublin, the park has an even-numbered area code (Dublin 8/D8). All other areas of northside Dublin (except for the adjacent Chapelizod) have odd numbered area codes, and even numbers if on the southside of Dublin.
