The National Botanic Gardens at Glasnevin was established in 1795 by the Dublin Society at the behest of the Irish parliament and was conceived as a great national institution for the betterment of the scientific community. The Botanic Gardens extend to over 50 acres on land acquired by the Society, bought from the poet Thomas Tickell. This complex of three interconnected glasshouses is one of several such structures on the site, dating from the period 1854 to 1966. Each house housed a particular plant group.
