Appraisal

The National Botanic Gardens at Glasnevin was established in 1795 by the Dublin Society at the behest of the Irish parliament, conceived as a great national institution for the betterment of the scientific community. The complex extends to over 50 acres on land acquired by the Society, bought from the poet Thomas Tickell. Commissioned by Fredrick Moore as part of a series of significant improvement works and expansion undertaken during his directorship, the Great Palm House was erected to replace the condemned former glasshouse which was badly damaged by a storm in the years before. It was constructed by James Boyd in Paisley, Scotland as a prefabricated kit and erected in Dublin over a period of nine months from March to October 1884 at a cost of £800. The flanking wings of the original house were retained and have been altered through the years. By the early 2000s the Palm House had fallen into extensive disrepair and was closed to the public. A significant and faithful restoration was undertaken from 2002-4 resulting in many of the original cast-iron elements being recast and reinstated. This building represents a considerable engineering achievement and is one of the largest of its kind in the world. It hosts many good-quality features, including the floriate capitals to the internal columns, which are also particularly apt for a building housing plants. The Palm House is the largest structure within the Botanic Gardens and contains a substantial collection of horticultural species of national and international significance. The historical and cultural interest of the Palm House is enhanced by its association with the celebrated philosopher, Ludwig Wittgenstein, who often visited during his residency in Dublin, as indicated by a brass plaque.
