The Palm House is a greenhouse located in Botanic Gardens. It is one of the oldest examples of curvilinear iron and glass structures still surviving in the world.

It was built by Richard Turner of the Hammersmith in Dublin in 1839 to a design by Charles Lanyon.

It predates the glasshouses at Kew Gardens in southwest London and the Irish National Botanic Gardens at Glasnevin, Dublin, both of which Turner went on to build.

The Palm House consists of two wings, the cool wing and the tropical wing. Lanyon altered his original plans to increase the height of the latter wing’s dome, allowing for much taller plants.
