Belfast, Northern Ireland - Palm House Botanic Gardens - The Palm House is one of the earliest examples of a curvilinear and cast iron glasshouse. Its constuction was initiated by the Belfast Botanical and Horticultural Society in the 1830s. The two wings were completed in 1840, and were built by Richard Turner of Dublin, who later built the Great Palm House at Kew Gardens. Over the years, the Palm House has acquired a reputation for good plant collections. The cool wing houses all year round displays of colour and scent using plants such as geranium, fuschia, begonia and bulb displays. The stove wing and dome area contain a range of temperate and tropical plants with particular emphasis on species of economic value. The gardens contain the Tropical Ravine, Rose Gardens and fine herbacious borders.
