The Botanic Gardens of Belfast opened in 1828 as the private Royal Belfast Botanical Gardens. It continued as a private park for many years, only opening to members of the public on Sundays prior to 1895. Then it became a public park in 1895 when the Belfast Corporation bought the gardens from the Belfast Botanical and Horticultural Society.
Occupying 28 acres (110,000 m2) of south Belfast, the gardens are popular with office workers, students and tourists. The gardens' most notable feature is the Palm House conservatory. It was completed in 1840. It is one of the earliest examples of a curvilinear cast iron glasshouses in the world. 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. In the past these have included an 11 metre tall globe spear lily. The lily, which is native to Australia, finally bloomed in 2005 after a 23-year wait. The Palm House also features a 400-year-old Xanthorrhoea.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
