St Stephen's Green is a city centre public park in Dublin, Ireland. The current landscape of the park was designed by William Sheppard, which officially opened to the public on Tuesday, 27 July 1880. The park is adjacent to one of Dublin's main shopping streets, Grafton Street, and to a shopping centre named for it, while on its surrounding streets are the offices of a number of public bodies and the city terminus of one of Dublin's Luas tram lines. It is often informally called Stephen's Green. At 22 acres it is the largest of the parks in Dublin's main Georgian garden squares. Others include nearby Merrion Square and Fitzwilliam Square.
