The gardens were founded in 1795 by the Dublin Society (later the Royal Dublin Society) and are today in State ownership through the Office of Public Works. They house approximately 20,000 living plants and many millions of dried plant specimens. There are several architecturally notable greenhouses. The Glasnevin site is the headquarters of the National Botanic Gardens of Ireland which has a satellite garden and arboretum at Kilmacurragh in County Wicklow.
