St Stephen's Green, known in Irish as Faiche Stiabhna, is a public park located in the heart of Dublin, just off Grafton Street, a major shopping street in the Irish capital. Previously, the streets surrounding the park were vital for traffic in the city center, but since a city ordinance in 2004, traffic on those streets has been significantly reduced.

The park is rectangular in shape and was formerly part of the outskirts of the city, used primarily as pastureland for livestock. However, in 1663, the municipal government decided to close and sell the adjacent land, surrounding it with a wall the following year. During the 18th century, the area became a residence for Dublin's high society, with the construction of many Georgian-style buildings around it. Today, most of the buildings are replicas of the originals.

In 1814, control of the park passed into the hands of a commissioner representing local residents, who decided to replace the wall with a fence and restrict access. It was not until 1877 that free access to the park was allowed again, thanks to the intervention of Parliament following an initiative by Arthur Guinness. Guinness funded the remodeling of the park in 1880, which has remained largely unchanged ever since.

During the Easter Rising of 1916, the park was seized by IRA insurgents, but they were eventually put down by the British Army. It is said that during the fighting a cease-fire was declared to feed the park's ducks.

The current design of the park, with its central lake fed by the Great Irish Portobello Canal, is due to renovations carried out in the 19th century.
